UMC Interface Screw Clamp Bracket

I have a Behringer UMC404HD. While it's a great interface, one of the flaws is that there are inputs and outputs on both the front and back of the device, which makes it hard to find a good place for it with good cable management.

I have a desk that I did not want to make any destructive changes to. Instead of screws or adhesive, I changed this existing clamp-on headphone holder to a bracket to house the interface

It's not perfect. Ideally I would prefer the front of the interface to be flush with the shelf it is hanging off of. It has held up in PLA for a few days now, but I am concerned it might not be strong enough over time and might need re-printed in ABS. The right side does not sit perfectly flush because the USB cable is plugged in, and the left side would have the same problem if you need to use any of the Insert jacks.

The right piece is just a mirror of the left except for the threads (so both are right-hand thread). These should work for most of the other Behringe
