With recently adopting a puppy, I needed something to protect the wires for my 3D printer. Something strong. So I modeled 4 different versions of the cable/wire protector & manager. Simply mounts to the wall using two drywall screws. 

V1 organizer I have split into 3 parts for ease of printing.

Print w/ 4 walls, 15% infill and yes, supports.

Thanks for looking and let me know if you have any questions!
