Modular Spool Holder

This is a spool holder I made where the roll of filament rests on 4 small wheels.
It was designed to fit a spool from AddNorth which is around 20cm diamater, 5.5cm wide where each side is 4mm thick.

Easy to customize the width to fit wider spools, just make the Connector part longer. This design is entirely modular and requires no screws. So it is easy to reuse with different spools without having to print a new holder and buy new wheels.

I'm using these wheels: http://www.clasohlson.com
