DISCLAIMER

The Files provided by the MODCASE EVOLUTION (EVO) and its CAD assembly are for experienced PC builders, as they are intended to be used with the user's own printer, computer parts, screws and cables. MODCASE EVO is committed to ongoing development, with recommendations for maximizing print strength and reliability included for best results. However, it is the user's responsibility to source parts and cables from reputable suppliers and to observe their new PC after building, running some real-world stress tests, and ensuring that the parts are not brittle or easily delaminated. Additionally, the quality of the printed case may be affected by the filament, printer model, settings and any modifications made via CAD.

Detailed terms of use are outlined in our End User License Agreement (EULA) included with the files. By using MODCASE files, you understand and agree that Haiteng Pty Ltd, the owner of MODCASE, is not responsible for any loss or damage that may result from the use of the print files.  Otherwise, please do not use the files, contact support.

Overview

EVOLUTION ITX Assembly

Join the frame halves using 4 screws from the inside. 

EVOLUTION M-ATX Assembly

The M-ATX model comes in 4 splits to fit your print bed, they join using screws as shown below.

M-ATX 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. All 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

Part List

Materials

EVOLUTION uses 1 screw type for all. Both socket head and flat head screws are compatible.

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 and adjust its position if required.

 Note: v1.3 onwards no longer requires the housing (shown in yellow above).

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 P1p, P1S, X1C, X1, Prusa Mk3s+, Mk4, Sovol Svo1 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 - 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!

Note on Stringing:
Please dry the filament before printing. Otherwise, tuning print settings may not help.

See Troubleshooting section for drying tips.

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

Repeat the same procedure for the other panels and small parts.

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 - 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!

You can print more perimeters or even entirely solid for additional strength. However it's not always necessary and uses more material.

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 normal M3 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: If the ATX PSU is longer than 140mm, the max GPU length is 254mm.

Fans and Radiators

M-ATX 

2x 280mm radiators, on the side and the top

4x 140mm fans

1x 120mm fan at the back

ITX 

1x 240mm radiator on the top

4x 120mm fans

1x 92mm fan at the back

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. 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 is 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.
