Anet A8-B v1: X-Belt Tensioner

thingiverse

I did not get the original by FredGenius to print properly on my A8, so I drew a version with looser tolerances. I changed deliberately: - Tooth are much looser in the belt gripper (I used washers to fixate the belt after insertion) - Dove tail with wider tolerance and 55° angle instead of 45° - 3mm tightener screw instead of 4mm (just because I had those available) - tightener screw closer to the belt to reduce skew forces (all other changes just happened.) You'll need: **3mm x 30mm** screw (you can use one from the spare parts) **3mm nut** (also from spares) 4x **3mm x 17.5mm screws** (there are 8 of them in the original belt fastener) I swapped the 30mm philips screw with a hex nut screw I'd bought some time ago for better access.
