Ready to print with .2 mm layer height (need to add support for the drums on the bottom side). Also needs 4 PCS 608 Skateboard bearings.

I advise you to sandpaper the rolls from both sides to make them a bit shorter so they are not touching the holder, and to use a long air balloon rubber to increase the drag between the spool and the rolls, cause without it the spool tends to slip instead of rolling the rolls (also I think regular blue tape will work just fine too)
