Emma M. ★★★★★ Oct 22, 2026

Swapped this in for the stock gear on my Ender 3 and the 11mm diameter was a perfect match. The teeth grab the filament much better now, no more slipping during retractions.

Scarlett ★★★★★ Oct 21, 2026

The 5mm inner hole fit perfectly on my printer's stepper shaft without needing any shims. The teeth bite into the filament noticeably better than the old worn gear I was using.

Riley V. ★★★★★ Oct 20, 2026

I've been swapping gears on my printer and the 5mm inner hole on this one lined up with no wobble. The 7mm toothed section gives the filament a solid grip without skipping, which solved my under-extrusion issues.
