Dévidoir filament

https://www.thingiverse.com/thing:4441076 presented a thumb screw to replace the wing nut on the front-left corner of the BIBO bed. It is too wide for the other two positions.
I have created a smaller version to fit the right-front corner and the back-center.

A M3-.50 nut is required.

Dévidoir de bobine de filament, je l'ai fixé sur un vieux moteur RC (d'avion) de 28mm
