BondTech Mini Extruder with PC4-M10 fitting
thingiverse
I've made a modification to the Bondtech Mini Bowden Extruder for Raise3D N2 found at http://www.bondtech.se/en/products/freebies-stl-files/ to make it fit PC4-M10. I'm using this with Bondtech DualDrive gears for 1.75 mm filament, which can be purchased from Bondtech or Prusa (note: requires permission to buy spare parts). Modifications include: PC4-M10 Pneumatic Fitting Better cooling Improved filament loading (may cause issues with flexible filaments) Increased space around gears Space for M3 nut Edit 2018-11-27: This extruder demands a powerful stepper motor and strong stepper driver like the S109 (Toshiba TB67S109). Alternatively, you can purchase a 3:1 geared Bondtech BMG. Due to their removal from the original website, I've uploaded the files BondtechMini_Bowden_1.stl and BondtechMini_Bowden_2.stl with a revised license.
