Fidget: Đồ chơi bánh răng xoay

The model is available with 3 different gears with 2:1 ratio: spur, helical and double helical, you pick you like the most.

How to print: firstly print two gears and then a base with a pause* on 7.8mm, on pause place two gears and complete the print. It all takes around 15-20 minutes to print.

It’s fun to spin those with compressed air, be careful ;-)  

Also I’d like to see your suggestions

*I would suggest to add a small purge tower and make it to print before the layer that does after you insert gears. It will make all oozes not effecting the print at all. Added an example .3mf file.
