Aquarium Scraper

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. 

Handle removed, added a mounting section with a captured M3 nut for setscrew to attach a longer handle.  Two stl versions made, one for ¼"x1/2" rectangular bar, the other with a 9mm hole.  Both fit common fibreglass rod shapes.  For anyone who wants to fit to a custom handle, I've included a .step file with no hole.
