Gear replacement branch cutter fiskars

My father brought home this cheap plastic ( PA-GF or Nylon+Glass Fiber) trench-cutter that he broke in the intent of cutting a old branch, immediately i thought about replacing the gear part with a 3d printed one!
The model is "Fiskars 112290".

I used Reelfill's PETG with 100% infill, 235°C extruder, 0.4 mm nozzle
You can find Reelfill at www.reelfill.com and www.zyx3d.it

Here are some photos and the STL if you need it, on the left you can see the broken part, the second one and the thir
