Formbot T-Rex Cable Management

Due to Thingiverse's poor decision to begin blocking downloads and forcing ads without any improvements to their site, I am abandoning Thingiverse and moving all my models to prusaprinters.org:

Since we all know it's in bad taste to mount our spools directly to the top of a printer frame (Since it intensifies defects from vibrations), I modeled some pieces to replace the spool holders at the top of the Formbot (AKA Vivedino) T-Rex 3 (also works for 2+) that allow you to continue to keep the cables managed and out of the way.

I also included an additional hole for more proper mounting of the key ring for the strange T-Rex 3 "cable tensioners"
