NEEDED
NOTE: Supports are somewhat difficult to remove.
NEW: The V2 model has taller lobes on the ends of the roller holder to keep the spool from sliding off of the end.
The bearings should fit snug into the housings, but the ends of the roller rod will need to be glued into place (or not, it seems to work fine without glue too). The roller does have a bit of wiggle without glue, but with a small amount of pressure it seems to grip the bearing just fine. This is a simple roller I made for fun, it seems to work well.
The author marked this model as their own original creation.
