Itty Bitty modification for NEMA-17

thingiverse

I created the Enhanced Dual Extruder by clough42's design. It features a powerful NEMA-14 stepper motor and offers excellent performance. I've noticed interest in a NEMA-17 version, however, unfortunately, no such option is available from the manufacturer. I decided to take on this challenge and modify the original extruder's main body to accommodate the larger motor size. The initial prototype has been created and it works as intended. Although there were some limitations due to time constraints, it functions well for testing purposes. For optimal results, a 1/8" all-thread rod must be threaded through the filament paths to achieve smooth movement. I preserved the exact same shaft distances so that users can reuse their belts.
