Filament roller experiment

Update: I updated the rollers due to problems with almost empty filament rolls; they aren't heavy enough and the friction just tops them off the holder.
The new rollers are based on bearing idea I saw in Thingiverse some time ago. I didn't find the thing, but modeled my own. Rolling just fine. The model has tolerance of 0.1mm. Use horizontal compensation. feed rate etc. to make them print properly.

Wanted to test some ideas and needed better, adjustable filament roller. Soo I tested my idea
