Spare Gear For Mixer

I made lot of models with 3D printer during last 4 years.
Some of them were exposed on my stall at Maker Faire Prague 2021.
Now I would like to offer some of them for other 3D printing guys.

There is one small and cheap piece replacing original Gear For Mixer. 

It should be printed with support as you can see on the picture.

It can be printed from PETG filament with layer 0,2mm
