Belt tensioner Wanhao i3 plus

thingiverse

Another x-axis belt tensioner for the Wanhao i3 plus and possibly other models as well. It's remarkably rigid. To assemble it, you'll need two 4 mm bolts that are 6 mm long and one 3 mm bolt up to 30 mm with a nut. The original bolts can be reused for the belt itself. You can print this part using any infill percentage you prefer, but I chose 100% for maximum strength. The optimal print orientation for me was straight up with supports in place.
