Modular GPU Support System – Concept

This is a modular, 3D-printed GPU support system designed to prevent GPU sag while remaining compatible with a wide range of graphics cards and PC cases.

The system is built around two main modules and 1 pizza addon:

Threaded Height Modules

A fixed female column in different heights

Interchangeable male threaded supports in multiple diameters and lengths

Uses a buttress-style thread optimized for 3D printing

Provides high vertical load capacity with minimal flex

This allows the support height to be adjusted precisely while remaining stable under GPU weight.

Male colum 3 diffrrent to choose. Small og long GPU support options
Top Spacer Adapters (“Pizza Spacers”)

Placed on top of the support column

Same outer diameter as the column for stability

Different shapes to match GPU addon layouts:

Half disc – clears GPU fans

Center strip (1/3 width) – supports narrow edges

2/3 disc – supports angled or offset GPU frames

These adapters ensure the support contacts the GPU only where it is safe, avoiding fans, shrouds, or heatsinks.

Why This Design

Works with many GPU designs without custom modeling

Easy to print and assemble

Strong, stable, and adjustable

Modular system reduces the number of parts needed

This makes the support suitable for custom PC builds, 3D printing enthusiasts, and small-scale production.
