Dụng cụ tháo bánh răng truyền động (cảo) cho máy in 3D

When planing extruder upgrade on my Creality Ender 5 Pro I discovered that drive gear is push fitted on the shaft and there is no easy way to remove it (WD40 + pliers didn't work). So I've designed a small tool (a puller) to remove the gear. You need to print it strong, so 3-4 perimeters and 20% infill. 

Print on the flat back, no support needed!

Vitamins needed: M4 nut and any M4 bolt.
