Rolling/flattening Tool

thingiverse

This paper creasing tool is perfect for papercrafting and origami projects. It surpasses traditional methods like using your finger or bone folder as it doesn't slide on the paper surface. The tool requires only a bearing, which is held in place by a printable pin. You can find two sizes of .stls available: 1/4" Bore, 3/4" Outside Diameter, 13/32" Wide Double Row Bearing and 608ZZ Bearing. Print both the handle and matching pin; if you prefer, a correctly sized bolt can be used instead of the pin. A 40% fill rate provides optimal strength for printing. Trim the pin's bottom to make it round and test-fit it into the tool until it fits snugly. If needed, apply glue for extra security.
