This mounts a Focus Scarlett 2i2 audio interface (3rd generation) under a desk or table. It includes a large hook for headphones below. There is a smaller hook in back for extra loops of headphone cable.
I modeled this in Fusion360. Along with the .STL files, I've included .STEP files and .f3d files so you can modify the model in Fusion 360 or another CAD program.
Print with default settings. PLA or PETG is fine. Any layer height is fine. Print the bracket face down, and print the headphone hook with the right side down. I chose to use a textured build plate to give the front surface a pebbly look.
Have fun.
The author remixed this model.
This is a new design inspired by jangrewe's model. I copied the basic look and location of the desk screws, then added the headphone hook and used it to retain the Scarlett in the bracket.
