I was yet again looking for a spool holder that would properly feed my 2.5kg spools to my A1 mini. Those carton spools are not really good at rolling on their own rendering my previous upload unusable for them (works fine with plastic spools!).

Then I found this great design and created an A1 mini print profile which would fit great onto the smaller build plate. It assembled just fine and it is working great as of now.

You need 3 M5x20mm screws and 3x M5 Nuts to fully assemble this one. The 608zz bearings are on the third plate if you want to try out self printed ones. So far they work great (added a little industrial lube just in case).

Big thx to Wesapatrar and HerGiz for their great designs over at printables.com:
