Gear heart fidget toy keychain V3

This is a version of my original model Gear heart fidget toy keychain . 
In this version you don't need an extra part to secure the gears in place. The gear axes have 3 pins wich act like springs to let the gear through but spring back once the gears are completely through, holding them in place.
 

Disclaimer: if you know your printer has trouble printing fine details or your prints suffer from poor layer adhesion, the pins might break. I'd recommend you print version 1 or version 2 of this same model.
 

Self locking gears without the need of an extra part
