Custom Anti-Sag GPU Bracket

In the world of PC building, one common issue that almost everyone faces is GPU sag!

This occurs when the weight of the graphics card causes it to droop or sag in the PCIe slot, potentially causing damage over time.

While GPU Sag brackets exist online, they can still be moderately pricey (often around 10-20$). In addition to this, they usually look plain and boring and don't really match the computer's aesthetic.

To address this problem, I set out to redesign and create an improved and custom GPU sag bracket using Fusion 360 and Tinkercad!

The only parts you will need for this simple project are the following:

Some filament (I chose eSUN's Marble PLA+)

and of course, a 3D Printer!

I began by researching existing GPU sag brackets and identified some of their strengths and weaknesses.

Firstly, most GPU sag brackets had a screw top design in order to be adjustable and accommodate any GPU height. However, most of these brackets had small, round bases which meant that the bracket could easily slip if it was under a lot of weight. Furthermore, most of these GPU sag brackets were plain black/white which was extremely boring.

This meant that my custom re-design of the GPU sag bracket had to be adjustable, have a sturdy and stable base as well as a custom design in order to give it some personality!

I went straight into Fusion 360 in order to create a simple GPU sag bracket design.

It was composed of two pieces, a base with a threaded hole as well as a top piece with a threaded rod/screw!

While the main design was done, it still looked plain and boring, no different to the sag brackets online.

So, I imported the model from Fusion 360 into Tinkercad in order to give it a custom design. I wanted a fun but original look so I searched the web for some cool "circuit" design SVGs until I found the perfect one.

I imported the circuit pattern SVG I found online into Tinkercad and aligned it to cover both pieces. I then decided to create two versions; One where the circuit pattern was cut into the bracket itself and another where the circuit pattern was protruding outwards in order to determine which one looked the best once they were printed.

While I was designing the pattern in Tinkercad, I decided to also create a triangle shaped base to increase the aesthetics and stability of the bracket!

After exporting the model from Tinkercad, I printed the GPU sag bracket using my 3D Printer!

I used the following Cura settings:

• 0.12mm layer height
• 100% Infil
• Supports: On

For the model with the indented pattern, I decided to turn supports on which may be why the quality seems much better than the protruding model (I had supports turned off for that print).

After printing, simply screw the two parts together! There should be more than enough clearance but you may have to twist and turn it a bit to loosen the parts.

The entire print took around 4 hours each but the end result was definitely worth it!

PS: I attached the GPU Sag Bracket Files in this step!

Finally, after all that hard work, we can place it underneath our GPU to forever protect it from any sag it may have!

In hindsight, black PLA would of blended better with the rest of my computer but I like the bright and unique marble texture this specific PLA provided!

PS: Ignore the dust on the PC, I cleaned it out after I took the pictures!

While this design is amazing, there are still improvements that could be implemented into the GPU sag bracket design such as a magnetic base for the best grip or even modifying it to connect to the PCIe bracket of the PC Case for the most hidden support!

However, this was the best design for my needs since I don't have a large GPU and I love the obvious circuit pattern!

I hope you liked this Instructables!
