Please Read Before You Print

The main case shell is provided in two different versions:

• File 1: Original Cube (165x165x165mm) This is the "Proof of Concept" version seen in my video. This version is a perfect cube, but it is very difficult to build. You must modify the eGPU board by removing the PCIe 8-pin power connector and soldering the wires directly to the board. I do not recommend this. Only use this file if you are an expert and know exactly what you are doing.

• File 2: Deep Case (165x165x185mm) This version is slightly deeper (not a perfect cube), but it is much better for most users. It maintains a compact size but allows you to build the eGPU without any modifications to the board or power connectors.

How to Print

• Orientation: Place the main case shell with the front side facing down on the heat bed.

• Supports: Use standard tree auto-supports for the best result.

• Infill: Set infill to 100% (solid) for the best strength and heat resistance.

• Material: Use ASA or other high-heat resistant materials. Do not use PLA as it will melt from the GPU heat.
