Spool Holder Thing

Is one piece to make alignment easier - tried those two part ones and got sad.

Can hold a 5lb spool or the smaller ones. (I should add the metric size descriptions too.)

The little red part can hook over a table edge to keep the spool from reeling into the printer. Or you can put the red part in the other way to push against the printer to prevent it from reeling into the printer.

Uses 608 skateboard bearings and any nuts you have at hand. The ones in the sketch are 8mm, but 0.25 inch will work if you make the holes in the axle smaller.
