Over the years, roller shutter buffers begin to crystallize and eventually crumble. With 3D printing, you can create as many as you want, in just a few minutes, in the color of your choice.

For this model, you'll find two print profiles: a generic one for PETG, PLA, and all easily printable materials, and a profile with the model optimized for printing in GF or CF filled PA, which, due to the roughness of the surfaces, always appears "thicker" than desired.

The housing is for an 8mm hex nut and an M5 screw.
