Enclosure for ADT-Link UT3G External GPU

I designed this eGPU enclosure specifically for the ADT-Link UT3G, the Power Color Fighter RX 6600, and the FSP Flex Guru 300w PSU. I know this is very specific, but I was asked to share. It was designed in the free version of SketchUp, so unfortunately I can only offer stl and skp files. I figure it may also offer inspiration.

I designed it to be as small as possible for my parts, so your mileage may vary. The Fighter 6600 is a true 2-slot card, has a small fan shroud, does not have a backplate, and does not extend past the footprint of the UT3G. Your card installed in the UT3G will have to be no more than 135 from top to bottom, including the stock rubber feet. It also requires a 180-degree adapter for the 8-pin power, which can only add 5mm for 140mm top to bottom. Your Flex PSU will likely have to be modular as there is limited room for excess cables. Also I'll note the 6600 is a low power card. More powerful cards may require an enclosure with additional fans.

It is designed to be printed without any supports. Recommend PETG or other heat-resistant filament. PLA may melt or sag over time.

For assembly you will need:

• 4x M4x10 screws (recommend button head)
• 4x M4 threaded inserts with a depth ≤8mm
• 1x M3x20 screw (recommend socket cap)
• 2x standard M3 PSU screws

You will also need:

• Thunderbolt 4 cable with 90-degree plug on one end (adapters will likely hurt performance)
• 180-degree PCIe 6+2-pin power adapter
• If using FSP PSU, EPS 8-pin to PCIe 6+2-pin adapter (ensure has proper pin adjustment)

Assembly:

• Install the threaded inserts in the rear part.
• Remove center foot from UT3G and make sure to keep the foot and cap nut.
• Install the GPU into the UT3G using only the center support rod. 
• Thread the M3x20 screw through the bottom hole of the rear part far enough to slide the rubber foot back on.
• Insert the UT3G and card into the rear part without knocking off the screw and foot, and then reattach through the base of the UT3G using the original cap nut.
• Install the PSU and screw into place. 
• Attach cables and manage using a zip tie and hole in divider. 
• Attach USB and run out through the right hole at rear. Lock into place using plug.
• Slide front onto rear making sure the vent holes are on the GPU side and close with the M4 screws.
• Excess USB cable can be stored through the left hole and routed up the channel.
