HE+ Dual Drive Bowden Extruder

thingiverse

This dual-sided extruder is propelling the filament from both sides. The design remains straightforward yet has its limitations. It's optimized for 2.85mm filament but should also function with 1.75mm - if issues arise, I won't be held accountable. The extruder operates on my custom-built printer without any problems so far. However, a robust reliability test is still needed as my printing experience remains limited. Some necessary files can be found in my H3+Extruder design (available at thingiverse.com/thing:2277417). --------------------------- 2018-06-26 - Update: A body for the bowden clamp has been added, accommodating 6mm bowden tubing. These clamps are readily available on aliexpress. I've successfully tested a clamp designed for 6mm bowden but remain uncertain about its compatibility with 4mm clamps. If their outer dimensions match, they should work; otherwise, not.
