X-Acto #1 Handle Rollstop

Designed a quick and easy to print rollstop to prevent an X-Acto #1 Knife to stop rolling.Print upright and fit into the end of the knife handle. The tolerance is very minimal (0.2mm) so you might have to scale up depending on your printer.Remove all blades from the handle when attaching this as I cut myself when handling.Tested in PLA but will work in any filament.
