Easy open/close belt Extruder for 1.75

Hi !

I wanted a easy acces for a belt Extruder for 1.75
Inspire from https://www.thingiverse.com/thing:1764551 for sytem Hobbed Bolt & 60-GT2 aluminium pulley and https://www.thingiverse.com/thing:1579394 for easy acces.
It's very funny and fast to change the filament.
I printed and tested. It's been 3 weeks and it's really great. I will post photos soon.

Have fun !
