Made this so I could mount hotwheel tracks to the wall. Using either screws, doubsided tape or command strips. 

Udpate V1.1: Added additonal track support model with more support for the track.
Added additional models that have the mount and track support rolled into one piece, as well as added 22.5, 45 and 90 degree variations.

Recommend printing the mount and track support as one model with supports. I've printed a few of these just using basic settings.
