Works with x & y axis on the printrbot jr. Just print out, feed the tail of the belt through and ziptie. It should be a pretty tight fit, but I put in a drop of glue just to be sure.
I made some little feet to hold the screws, but ditched em at the last minute cause I cut the belts too short. :(

Materials and methods

zip ties
recycled nuts & bolts from printrbot jr.
