UM3/BondTech Feeder

UM3/BondTech Feeder

Description

Update V2: Notable updates: More reliable drive shaft and inner gear design, bearings on the tension arm for smoother, stiffer operation. Moved to more 6-32 plastic screws, so there are fewer unique parts to purchase. This is a V1 design for a feeder replacement for the Ultimaker 3. It uses BondTech drive gears, so you can run abrasive materials (the standard UM3 knurled drive is not hardened enough for abrasives, and will wear down).
