Reinforced gears for Kuros compact bowden extruder

Just broke off the original Kuro's Gear on my extruder. I printed it with 35% infill with white PLA but it didn't resisted to a clogged hot-end.

I modified the .Scad file to make a gear with more arms and a bit thicker. It's compatible with the original extruder body.
Now back in business with a nice extruder !

The modified extruder body with the M5-pneufit fit come from :
