I designed this tool to help crease paper when doing papercrafting or origami. It works much better than trying to use your finger or a bone folder since it doesn't slide across the paper.

The only vitamin needed is a bearing, a printable pin holds the bearing in place.

Instructions

There are .stls here for 2 sizes:

• 1/4" Bore, 3/4" Outside Diameter, 13/32" Wide Double Row Bearing

• 608ZZ Bearing

Print both the handle and the matching pin. If you don't want to use the pin a correctly sized bolt will also work. A 40% fill rate works great and provides plenty of strength.

Trim the bottom of the pin so it's round and test fit into the holes on the tool until it fits snugly. If you achieved a good fit, the pin won't need to be glued in. If you got it a little loose, a drop of glue will keep it in place.
