Filament Side Roller

Filament side holder. I made this to fit in my enclosure. Mounting it sideways worked perfectly. Is pictured with a small spool I bought by mistake but it also work with the 1kg spools I normally use.

It uses 2 604zz bearings and a 5/16 x 4 1/2 inch bolt to assemble. The bearings do fit tight as a press fit. When assembled, tighten the bolt to give it a little drag or the spool will be freewheeling on you and the filament will come off the spool. It will accept any size spools.

Print the parts flat, no support needed.
