OCuLink eGPU

This is a work in-progress eGPU dock for  OCuLink PCIe risers that supports GPUs up to 225mm in length and full ATX power supplies. This is the first multi-part printable model that I've made, so please go easy on me.

BOM:

• OCuLink PCIe Riser

• 3x 10mm M4 screws with 2x nuts (Add 2-4 if you want to screw down the riser itself, which I'd recommend)

• 2x 20mm M4 screws with nuts

• Superglue is helpful

• ATX 24-Pin power button jumper (this is the one that I used, any will work)

• 1x GPU < ~225-230mm (depending on PCIe power adapter location)

• 1x ATX PSU (modular is highly preferred

• 2x PSU/case thumbscrews

Fully assembled (the downloadable version doesn't have the logo on the front): 

The PSU and GPU sides have 3 holes for M4 screws, though they're still a bit loose, I'll need to add more attachment points. I used a bit of super glue for the back side. 

The PCIe riser slot is pretty snug and fit just right for the riser that I used, your mileage may vary. I did add washers under the riser, drilled some holes, and added a few self-tapping M4 screws to secure it down, though it should stay in place if the GPU is installed: 

The vents on the PSU side of things were a bit tricky to remove the supports from, so I'll try to make this a separate panel eventually: 

Everything inside, just with side and front panels removed: 

The side panels and front panel slide into place (the downloadable front/top panel covers the entire top of the box): 

The hole in the GPU-side should line up with the OCuLink port if you use the same riser that I did.

The base isn't complete, so I'd recommend modifying it to your own needs. This piece is hollow with a side port that I put a powered USB-C dock so that I could have only two parallel cables going to my laptop from the eGPU: 

Depending on which side of your device the OCuLink port is on, you may want to mirror this print.
