Beware that the bearing part might be difficult if done in the order suggested. I had to disassemble and do the bearing outside and use a clamp to force it. Depending how your printed your parts it might be a real tight fit. Lower the arm a bit instead of the top so that the constraint can drop in with the lead screw having more ‘play’. If not you wont be able to get it in if you do the bearing first.

I used a small piece of tape to initiate the roll and the push the belt and it went around. Took me about 5 seconds belt/corner. Works very good on these new idlers.

I would avoid Step 1 trough 6 until you install the ends. Literally no reason why you cant do it the other way. If you follow this way, youll end up struggling with not having all the bearings fall out.
