I liked the idea but didn't have a way to mount it under anything so I've done this to mount it to the wall. I've also added numbers and 2 holders for those random keys that don't have a ring installed. Print however you want to just don't complain if you mess something up.

DISCLAIMER: Not suggested to put more then 4 keys per hook without scaling up model!!! I tried to reinforce but with this design currently not possible to do so! Made with TinkerCad on laptop so fuck off if you say its too crude! Also sorry if your printer is small I have ender 3 pro and it fits on mine!
