The Very Different Extruder (VDE-100) in action on a delta printer. It's mounted on the original heatsink so I wasn't changing too many variables at once. Printing 0.05mm layer height PLA at 195C, 40mm/sec. 4000 steps per millimeter. Needs fine tuning for acceleration and retraction, but works all the same. Weighs 100 grams with the NEMA17 pancake stepper. A NEMA14 or even 11 would likely work just as well.
