EVOLUTION User Manual

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! The 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.

Part List

Materials

The EVO can use most commonly available M3x20 screws. The imperial equivalent #4x3/4 screws also work.

USB-C Port

Modcase is designed to use most commonly available components. This USB C cable is suitable for EVO M-ATX. Similar cables may also work.

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

Note: EVO v1.3 onwards no longer requires the separate retainer for USB-C.

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

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

Printer Requirements

1. Nozzle Temperature: 240°C 
2. Bed Temperature: 90°C 
3. Minimum Bed Size: APU 180x180mm  |  ITX 240x170mm  |  m-ATX 200x200mm

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

ITX comes in 2 splits, 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. 

Slicing guide - Main Frame

1. Load “Frame_R” in your slicer and select the following settings:

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!

Note on 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 when prompted to “load as single object with multiple parts”.

Parts with mesh have 2 BODIES, one dedicated for mesh, one for solids.

2. Enter the following print settings

3. Right click the mesh body in the objects panel > Select “infill” and “Layers and Perimeters”

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

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

5. Slice and 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.

Slicing guide - Small Parts

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 3 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.

Drive Caddy

EVO M-ATX : Up to to 3 x 3.5", 6 x 2.5" drives
EVO ITX : Up to to 2 x 3.5", 4 x 2.5" drives

EVO M-ATX PSU options

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 PSU up to 220mm long can be front mounted with the 2 piece bracket.

NOTE: 
- 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.

- SFX PSUs are also required for side mounted 240/280mm radiators.

Fans and Radiators

Note: A slim 140mm fan may be needed to fit 280mm radiators on the side when using MATX motherboards.

280mm Radiators and 140mm Fans are mounted on the side with optional mounts as shown below:

When mounting just 2 fans on the side, please use a "bridge" in the middle. They're included in the radiator mount files. See below.

Reset Button

A 16mm hole is available at the back for an additional reset button. Just push out the cover piece and install the same type of switch as your power button.

Scalable Feet

Stock height is 14mm. You can scale it via your slicer in the Z direction. Untick the uniform scaling box and type in the height you like.

Going lower than stock is not recommended. If you're lowering the feet height, be careful and make sure your screw doesn't reach internal components.

Alternative Side Panel

Side panels that simulate the looks of the vents are also included in your optional folder. The default mesh type panels (left) have greater airflow for the same mesh density.

Carbon Fiber reinforcement

Four Ø6mm x 300mm Carbon Rods (Link) can be inserted to reinforce the case. See diagram below.

This is optional. Any Ø6mm rod will work.
