For some reason, the belt clips on my printrbot weren't long enough so I had to make these longer ones. I don't know why the other ones didn't fit, I may have just fitted something wrong. Either way, this has fixed my problem!
This clip is 30mm long as opposed to the 15mm long stock ones. The allow for the Y belt to line up with the y stepper and bearings. The screw spacing, size, and footprint are all the same so just a simple swap will get you up and running.
