Replace your Ultimaker bowden system with a precise high performance direct drive flex shaft extruder from Flex3Drive. Options to fit Ultimaker Original and Ultimaker 2 3D printers. Available in both 1.75mm or 3mm flavours.

The new latching tensioner design makes manual filament changes real easy and real fast instead of using the slow LCD controlled filament change. Full access to the filament drive area and a constrained filament path that makes printing even the softest flexibles easy with your UMO or UM2.
