Designed specifically for use with the NavePoint 22U 2-Post Open Frame Rack with Casters (SKU: 00404145). Other similar models sold by Navepoint may work just as well but I can not verify. Let me know!

The holes on the sides looked like they could have had accessories mounted to them but I could never find anything for it online, so I decided to design my own component.

These are patch panels designed to accept any keystone insert. I personally use them for RJ45 terminations. The idea being that I could completely internalize the guts of my homelab and I wouldn't need to redo cable management or tear my server down every time I wanted to add a new networked device; I could just have external jacks that were easy to manage from the egress points on the posts and it would be really easy to add, move, or remove networked equipment and keep my homelab intact.

Patch panels are designed ever so slightly bigger than standard keystone inserts to accommodate for variances in 3d printers. They will wiggle just a tiny bit but will never fall out. If you have difficulty removing keystones, I personally use a 10WR Vise-Grip and I find that to be the perfect length and shape for most keystone inserts. Just make sure its adjusted carefully; so far I have been able to insert and remove keystones without damaging the model. The clamp point of the patch panel is slanted on both sides.

I can't offer much advisory for filament printers; maybe try the same thing? Let me know it goes.
