Sermoon D1 OMG Extruder and Heat Break Upgrade

thingiverse

Allows an OMG v2 3:1 reduction extruder to replace the stock extruder motor and drive. Combine with a smaller, higher torque stepper and this upgrade is lighter than the factory motor and drive. Needs 2- M3x5x6mm and 2- M3x5x4 brass heat set inserts, also need 4-3mm cap screws (I think I used 2-20mm and 2-25mm long screws) The hot end does not need to be upgraded but can be by drilling the filament hole to 4.1mm and replacing the heat break with a Ender 3v2 style heat break and a 17.5mm long spacer made from 7mm x 0.5mm wall thickness tubing. PTFE tubing can then be extended to the heat break through the spacer.
