Geared Bowden Extruder using Bondtech gears

thingiverse

3 Aug 2018 I am also working on a direct drive version, but have to wait for more btech gears to show up so I can test it. This will allow you to run the super short stepper motors like on the Titan. 1 Aug 2018 Update Uploaded the F360 and step files. Was looking for a geared bowden extruder that uses Bondtech gears and couldn't find one so I made one. The gears are from the Pitan which are 3:1. Pretty easy print, no supports required. Main body parts print rigid and gears print at a low layer height. I use PLA for mine. Steps per mm seem to be around 798mm. You will need: 2x M3 20mm 2x M3 30mm 2x M3 40mm 5x M3 nuts 20x5mm Compression Spring, you can experiment with whatever works for you. 1x PC4 - M6 coupler with 4.3mm bore Nema 17 Stepper motor 1x 40mm M5 hex head bolt 2x 695zz bearings 1x 1mm washer
