Overview

EVO ITX Assembly

Join the frame halves using 4 screws from the inside. 

MODCASE EVO Assembly Guide


Standard PC screws are used for PC components
 such as Motherboard and PSU. (#6-32*6)

 

EVO M-ATX and ITX2 Assembly

The new 'ITX2' and M-ATX model comes in 4 splits to fit 200x200x200mm print volume. They join using screws as shown below.

Modcase EVO mATX assembly instructions

 

Notes:
1. 4-Split side panels are located in Optional/Side Panels folder for 200x200mm print beds.
2. M-ATX and ITX2 uses a screw-less GPU retainer.

 

EVOLUTION APU Assembly

The APU frame is quite compact, it essentially slides on and assembles 'around' the electronics. To slide in the motherboard, please remove these 4 screws:


Tips:
1. USB cables are secured with normal PC case screws.
2. Attach ATX and IO cables before sliding the motherboard in.

 

Panels

👉Insert retainer clips before installing panels.

 

Small Parts

 

Vertical Base *New*

This mod lets you use your EVO vertically for a minimal foot print. 

You can optionally mount a USB hub up to 154mm long (e.g. this hub works well with a USB extension cable).

Shorter hubs are preferred for ITX. (e.g. this hub).

Vertical Base Tips:
1. You may not need to reprint your frames for this base! Self tapping wood screws can drive directly into the existing rear. 4 Positioning studs are included on the top of the base for easy alignment.

2. If you do reprint, new holes were added to the latest "Frame_RT, Frame_RB, Frame_R" files to receive this base. The extra holes are hidden behind 0.3mm of material for a clean appearance for those who don't need the holes.

3. Need more bottom cable clearance? Scale "Base Feet x4" in the vertical direction only in your slicer (untick uniform scaling). This will result in taller feet, it's designed to work even after scaling.

4. Feel free to try other rectangular hubs, you may just need to adjust your mounting tape thickness for a centered fit. Use CAD files for further customization.

👉Make sure to cut the rubber tabs (it's soft) and use standard computer screws (#6-32 -6) to secure the cable.

 

USB Type A  - Also need to trim the rubber tabs before use.

 

 

Printer Requirements

  1. Nozzle Temperature: 240°C 
  2. Bed Temperature: 90°C 
  3. Required Build Volume:
    Model Build Volume
    APU 180x180x180mm
    ITX 240x170x200mm
    ITX2 (NEW) 200x200x200mm
    m-ATX 200x200x200mm

Any printer meeting the above specs will work.
E.g: Bambulab A1, P1p, P1S, X1C, X1, Prusa Mk3s+, Mk4, Sovol SV01 Pro.

ITX and APU models come in 2 splits. ITX2 and m-ATX has the new 4 split assembly.

Like games and GPUs, higher end printers will render nicer looking prints. Older printers can get a good result, but may require more Troubleshooting to get started.

    Bed temp must be 90°C for proper PETG bed adhesion. Use a 'brim' or glue on the print plate if you're still having lifting prints.

     
    2. Slice and Print!

    Evo Rear Sliced and Ready to Print

    Notes:
    1. All models are pre-oriented
    in their optimal print orientation. You do not need to rotate any models when printing.

    2. If you have stringing. 
    Please dry the filament before printing. Otherwise, tuning print settings may not help.

    See Troubleshooting section for drying tips.

    Slicing Guide - Mesh Panels

     1. Load “Door_R” in your slicer and select 'yes' if prompted to “load as single object with multiple parts”.

    Infill Perimeter Select Both


    4. Set the mesh to: 36% Grid infill, 0 perimeter, 0 top and 0 bottom layers.

    Evo Mesh Slicing Density settings

    In Bambu Studio, select the mesh via the objects tab.

    This dedicated body uses native slicer infill geometry to generate fast, clean and strong meshes. Reduce infill speed if you see broken mesh.

     

    5. Slice and print!

    Modcase Evo mesh sliced and ready to print

    👉Repeat the same procedure for the other panels.

     

    Note on Supports:
    Modeled supports are included for critical overhangs. For best print success, do not turn on additional supports. 


    Optional mesh customizations

    The mesh can be customized without CAD. Simply set your own density and infill type when printing.

    E.g. Use triangular infill with 30% density. This means the mesh will be weaved as triangles and with an open rate of 70%.

     

    NOTE: Watch out for elephants’ foot, as it can restrict airflow. Elephants foot can be controlled via first layer flow adjustment (Cura) or via the Elephants foot compensation setting in others.

    Notes:
    1. The GPU Retainer has an optional mesh body. You can assign mesh parameters like the side panels above to have a breathable mesh window, or you can just leave it solid.
    2. The Feet is best printed in TPU. Please follow TPU settings according to your filament.

     
     

    Optional Parts

    Removable Filters

    Intakes such as the top and side panels have removable fine mesh for dust filtering. For example, the ITX model has the following filters:

    The exhausts are relatively open for unobstructed heat dissipation. The PC should be set up with positive air pressure.

    The Part List has a full list of filters available.


    Cable management strap points

    Up to 12mm wide cable management straps or zip ties can be fitted to the following 4 positions.

    Metal Nut Inserts

    M3 locknuts can be inserted into dedicated pockets behind most holes, to be used with M3 machine screws.

    Please consider this as a backup option only. The self tapping screws have a lot of thread engagement and are quite reliable.

    (In optional folder: 3.5In HDD_Top.3mf Left, 2x2.5in Drive Mount.3mf Right.)


    PSU options for EVO M-ATX and ITX2

    Mount the PSU to the bracket first, using normal PC case screws. Then the bracket to the case with M3x20.

    SFX and SFX-L can mount to the side or the front. Mesh filter is available in the 'optional' folder.

    ATX PSUs can be front mounted with the 2 piece bracket.

    Notes: 
    1. SFX PSUs are recommended for full GPU length support. If the ATX PSU is longer than 140mm, the max GPU length is 254mm. Even then, some 140mm modular ATX PSUs have cable exits that reduce GPU length support.

    2. SFX PSUs are also required to make space for the 3.5" drive caddy or side mounted 240/280mm radiators.

    3. Optional ATX PSU mounts for taller right angle power cables is now available in your optional folder.

     

    Fans and Radiators

    CAD

    Crafted by direct modeling CAD, these files gives you full access just like its creator. The simplicity of the drawing means you'll find clean forms and features that can be adjusted either by dragging or entering numbers. 

    This CAD file is created from the ground up and delivered in the universally compatible STEP format. There are no hollow bodies or inoperable surfaces. Just clean, fully detailed and functionally interactive 3D models - that is ready to print. (Edit examples below)

    It's a complete CAD assembly with all the optional parts as well, continuously updated and always accessible via your unique download link.

     Recommended CAD Program: Autodesk Fusion 360 (free)

    Opening the File
    File > Upload > Select Files > Choose file > Upload.

    Enable Direct Editing
    Right-click top component in Browser Tree on the left > click "Do not capture Design History".

    Export
    Right-click a body> Save as mesh > Choose "3MF" > tweak refinement (optional)> Save.

    It's recommended to export as 3mf instead of STEP for printing for resolution controls and generally better slicer compatibility.

    • Move Walls, Adjust Thickness
    • Custom Front IO
    • Custom Water Cooling Mods
    • Create RGB Lighting Accessories
    • Create new mounts and accessories
    • Create molds
    • Create new vents
    • Add more PCIE slots
    • Resize case
    • Split Bodies

    Proceed with caution. Please understand, by altering the CAD you're changing the structure of the case itself. Ensure at least a 4 to 1 safety factor when designing your structures.

    To expose issues and speed up testing, you may want to consider test prints with only 2 walls, 2 top and bottom layers. This will reduce printing time and create an intentionally weaker print to expose any structural issues.

    Troubleshooting

    How to print stronger
    1. Dry your filaments prior to print.
    2. Print at the upper material temperature limit.
    3. Reduce print cooling.
    4. Higher mesh density.
    How to print for better appearance

    The following is an oversimplified list of factors that usually produce nicer looking prints, some affect strength.

    1. Use a lighter filament color or one with matte finish.
    2. Print at colder nozzle temps.
    3. Slower external perimeter speed
    4. More print cooling.
    5. Faster travel speed.
    6. Try Arachne perimeter generator.
    7. Service the printer (lube, loose screws, belts, defects)
    8. FDM prints look better in a soft lighting environment in general.
    Stringing
    1. Dry your filament. Otherwise tuning settings won't help.
    2. Check your retractions. Bowden ~2.5mm. Direct Extruder ~0.8mm (Varies with printer, normally it should be settings from your manufacturer.)
    3. Set Z-hop to 0 or 0.1mm (Lift Z)
    How to dry filaments

    - Using your oven. Set to 60°C and put your filament roll in it for 24 hrs.

    - Using your 3D printer. Set your print bed to 70°C, put the roll of filament on the bed and cover it with a box. The box doesn't need to be airtight, so the moisture can escape. Leave it there for 24 hrs.

    - Using a good filament dryer like the Eibos dryer, or one that can go up to 55°C.

    Ghosting (Rippling Edges)
    Ghosting can be helped by slowing down external perimeter travel speed. You may also want to reduce acceleration and jerk values, specifically for the external perimeter if your slicer has the granular setting.

    Alternatively, just reduce printing speed globally. 
    Print with 0.6mm nozzles

    All print settings are the same as 0.4mm except infill% for the mesh. You’ll need to increase density - a 40% mesh for 0.4mm nozzle is similar in hole size as a 50% mesh printed with 0.6mm nozzle.

    It is best to print the side panel retainer clips with 0.4mm nozzle.

    Post Processing (cleanup)

    Some overhang will occur in these 2 areas of your print. These are factored for in testing; they're internal and do not affect function. You do not need to tune your printer for these areas.

    Allowed Over HangsYou may need to trim some small bits of plastic sticking out, there's no need to reprint. For the most part, overhanging features have been mitigated with angled geometry.

    For example, the side vents start their lowest end on the inside, leaving the visible side perfect as it is the top of the vent strut.

    Material Saving

    If you are confident of your layer adhesion, you can step down to 3 perimeters to save on some material on the smaller models.

    4 wall is recommended.

    Broken Clip

    If you're having issues, try the following:

    1. Press P to access 'paint seam' feature in PrusaSlicer or Bambulab Slicer.

    2. Paint seams on the back of the thickened middle area. 

    This ensures the thin features of the clips are free from any seams that may weaken it.

    Broken Mesh

    Option 1. Set sparse infill line width to 0.5mm

    Bambulab: Quality>Line width>Sparse infill>0.5
    Prusaslicer: Print settings>Advanced>Extrusion Width>Infill:0.5

    The above is for 0.4mm nozzles. For fixing broken mesh on 0.6mm nozzles, set it to 0.7mm.

    Option 2. You can reduce sparse infill speed by 30%.

    Prints lifting or curling corners

    For PETG – Clean your bed with alcohol and ensure bed temp is 90°C.
    For PA, PC, ASA, PC-CF - try glue stick, use a actively heated print enclosure and 110°C bed temp.

    Cracking, brittle or delaminating prints
    1. Dry your filament again. The surface area of a spool of filament is immense. In open air, it can absorb enough moisture in 1-2 days to cause noticeable stringing, uneven walls, and bad layer adhesion.
    2. Increase nozzle temp. Normally nozzle temp shouldn't exceed 250°C,
    3. ASA, ABS, PC and Nylon really should be printed using an actively heated enclosure. Otherwise, you may end up with a print that is prone to cracking.
    Supports hard to remove

    If using Slic3r based slicers (including PrusaSlicer), set support "style" to Snug, and "XY separation between an object and its support" setting to 100%.

    Restrictive mesh

    Your first layers might be squished and flare out, making the holes smaller.

    To fix: reduce first layer flow in Cura, or in PrusaSlicer increase elephants foot compensation parameter.

    For expert printers: you can individually control the first 4 layers by using the following custom GCODE before layer change.

    {if layer_num==0}M221 S92{endif}
    {if layer_num==1}M221 S98{endif}
    {if layer_num==2}M221 S99{endif}
    {if layer_num==3}M221 S100{endif}

    S Value = flow percentage. You many try your own S values too. Each line of this code instructs flow % for that layer. By having full control of the first few layers, you can eliminate elephant’s foot, and even shape a tapered leading edge.

    Custom leading Edge Gcode
