Strong mATX 10" 2U-Rack Plate – Support-Free Design

It has been tested on a KWS 10" rack and fits perfectly. This point is important: to minimize bending and long-term creep, the plate is supported both on the front panel and against the inside of the back panel.

I designed this because many existing rackplate either did not fit properly mATX+GPU or required a ton of “dangerous” supports that can easily damage the part or cause the print to fail. This design avoids those issues while remaining sturdy and easy to print.

Hardware Required

• 6× Voron-style heat inserts M3×5×4

• 6× M3 motherboard standoffs (spacers)

• 6× M3 motherboard screws

• 6× M5×10 screws to mount the plate to your rack

GPU Compatibility

You can also install a GPU.

For reference, mine is 240 mm long and it just barely fits. 
Depending on your GPU length, it may extend slightly outside the rack. You'll need to modify sligthly  the model, if that what you want.

If that happens… it might be time to upgrade to a 19" rack or use a proprer case lol ;)

About the Design

This is not a “by-the-book” standard-compliant design.

Ideally, the front panel should have been 5U or 6U to fully cover the space occupied by the motherboard and GPU inside the rack.

However:

• Designing it strictly for 10" format makes it almost impossible to properly fit additional components.

• Creating a fully custom 6U front panel with custom buttons and layout would make the design much harder to share and reuse.

So this is a practical compromise between compatibility and usability.

I am currently designing custom front panels to fit fans and other cool features. I might share those as well.

Printing Instructions

• Material: PETG, ABS, or ASA

• ❌ DO NOT USE PLA :  PLA does not handle heat well and may deform over time.

• Supports: Not required

• Orientation: Place the front panel facing the build plate to get a clean textured finish.

• You’re a grown adult choose:

  • A decent infill

  • A solid number of perimeters

  • Layer height doesn’t really matter, it will only affect print time, and you’ll barely see the part once installed anyway.
