Belt protector (1 ball bearing block) for Cocoon Create 3D (Wanhao Duplicator)

thingiverse

I designed a belt protector for the Cocoon Create or Wanhao Duplicator, featuring a roller wheel design. It attaches to one ball bearing block only, so you'll need the '45mm long' ball bearing mod if you haven't already installed it (refer to attached photos). Two 3mmx10mm hex screws and two 3mm nyloc nuts secure the protector in place. The thin arms that insert into the block's holes were a challenge, but I solved the problem by adding masking tape for extra thickness - now it functions perfectly (you can modify it at your convenience). This belt protector was printed with clear ABS. Update: If you experience friction between the belt and its top or bottom grooves, try adjusting the position of the belt tensioner (a photo is worth a thousand words... see image #6). Happy printing!
