Pinion for automatic chicken coop door

A few months ago I bought an automatic door for my chicken coop through an online shopping portal. 

After a while, I saw that it stopped working and apparently the plastic pinion (very soft and poor quality) that is attached to the motor shaft had broken. Obviously I couldn't find any type of replacement, so I decided to replicate the model by making my design.

The result was easy and totally satisfactory, the door now works perfectly.

Printed in Petg and with a layer height of 0.15

*You can use the same screw that the original sprocket included and if you add a light touch of superglue even better.

I hope it helps you!
