I added another spool handle to fit 10cm wide spools with a minimum hole diameter of 3 cm, as of a user's request. Also, I changed the naming convention for this spool handle to make the dimensions more visible at first glance. I will update the naming of the two other handles at some point in the future.

I upgraded my Original Prusa MK2s with the fabulous Full Bear Upgrade and was in need of a new spool holder. As the upgrade consists of aluminum extrusions/profiles, attaching a spool holder to these profiles seemed to be the logical step. However, I wanted an easy and simple solution without lots of parts which could fit a wide range of spools.

So here it is, my simple spool holder for a majority of filament spool sizes!

I divided the spool holder into the aluminum extrusion mount with a 16mm inner threaded hole and the spool holder handle. This way one can exchange the handle with other gear like broader/narrower, longer/shorter handles, camera mounts and so on.

The only other parts needed are two M5 t-nuts and two M5x10 screws. I provide affiliate links to these parts down below.
