This kit is designed for the Prus i3 3D DIY printer. The gears are supplied as a set consisting of a primary drive wheel with an M3 adjusting screw and will fit a 5mm shaft with a flat side as is the case with standard Nema17 engines.
this gear kit's spring is 0.8mm wire diam, 5mm idm 15mm length. A secondary drive wheel with integrated high quality bearings and a shaft diameter of 3.00 length 20 mm made from precision ground hardened steel.
Dual drive gears for 1.75mm filament, precise custom CNC machining with extreme precision guarantees you get the grip you always wanted.
