This is a little cable caddy that's made to screw onto the back of any 100x100 VESA compatible monitor or TV. I was inspired by this, though this was made entirely from scratch to fit 100x100 instead of 200x200. The print itself is pretty simple, and should be done pretty quick depending on your settings (my Ender 3 was done in one hour at 0.4mm layer height). I did include a version of this that has little support beams in case you want something with more strength, but then you won't be able to put cables in and out through the top and will need to feed them through.
Any (Though Will Affect Strength)
You will probably need to use supports if you're printing the "beams" version of this.
