Eurorack Patchbay / Pass Through Panel using Keystone Jacks

I am currently in the process of organizing and moving some audio / eurorack gear into a 19" server style rack. 

While searching around for a patchbay I didn't find anything I liked without having to use a lot of adapters; so I made my own that will fit directly in eurorack rails. I know needing a front-to-back style patchbay is a bit of a niche for eurorack, but 19" rack mounting and a few 10 foot cables allows me to keep my midi controllers/keyboards on my desk while not clogging it up with my ever growing collection of gear. I also have my computer rack mounted, so being able to have as many front facing USB / network ports always proves invaluable.

No supports needed.

The 16hp x 16 and 12hp x 12 were printed in Bambu's new PETG HF, and the red 4hp x 4 is in Bambu PLA Tough. 3 walls with an extra alternate wall, 15% infill. But almost any material should work, and I' ve found the keystone jacks fit tight, but are also easily removable.

These accept keystone jacks which come in many different plug styles: 3.5mm, USB A/C, RJ45 Ethernet, RCA, Banana plugs, etc.

These are the jacks in the picture, the USB one I already had, but there are a lot of options:

This is a work in progress. I will be updating as I get everything mounted / make more sizes. 

EDIT 1:   Ive added a 30hp 1U Intelligel sized file as well. It is not tested, but its there.   :)
