printrbot simple string tensioner

thingiverse

fix that drift y or x axis on your simple! Instructions I'm not sure if this will be of interest to anyone or not but here is a tensioner for the string drive on the simple. print out, multiples work better, drill out the hole and screw in a m3 or 4-40 screw. Tapping is not necessary. Tie the string around the screw head and tighten. This is probably self explanatory by the pictures. it is a press fit onto the plywood. you loose aproximately .25" travel when used on the x axis, my bot couldnt get there anyway.
