This is a scraper blade holder meant to attach to a long, non printed handle. This is designed for cleaning aquariums. Uses a single edge razor blade.

The blade holding portion was obtained from MasterMaker333's RazorBladeHolder2 design, found on thingiverse.

This design uses a captured M3 nut so a setscrew can be used to mount it to the handle.

There are two stl versions, one for ¼"x1/2" rectangular bar, the other with a 9mm hole. Both fit common fibreglass rod shapes (the rectangular bars are used in chain link fences, the round ones as driveway markers). For anyone who wants to fit to a custom handle, I've included a .step file with no hole.
