LED strip track holder

just a track to fit various kinds of LED strips. read comments for more appropriate variable sets within the scad. the "heat shrink" refers to normal heat shrink because i often use clear heat shrink to waterproof LED strips instead of the terrible version of waterproofing you get from the pre waterproofed ones. print on end, my taz can print 250? so if you need to change that then the code should be straight forward. this wasnt meant to be published (as most of my messes) so i apologize for its poor presentation
