1set 3D Printer MK3 Drive Gear extruder Dual Gears kit DriveGears Extrusion Wheel for Upgrade Prusa i3 MK2 MK2S MK2.5 3D Printer (5mm bore)

Kits came complete (have ordered four now) and are of much higher quality machining than the images imply. No roughness, no sharp edges where they shouldnt be, could probably lift my printer by its filament with the grip they provide. Finding an STL that matched my setup was a PITA; had make one from scratch. Still, A+

Gears are great. I had to adapt my Mk8 extruder to use them but a new spring arm and updated stepper placement and its working great.

Just what I needed to stop the slipping. Remember to check the teeth for wear

Item was exactly as pictured and fit perfectly into my dual drive extruder.

They fit and worked perfectly on my 5 year old prusa.

perfecto estado estpy probando

The real deal. Way higher quality than my BMG clone came with. Wish I would have got these sooner

The extruder gears work as expected. Right now Im using them for my cr-10 and a thingiverse extruder holder.

Perfect as part of my DIY Prusa Mk2.5s upgrade.
