UPDATED Aquarium Algae Scraper Razor Blade Holder

If you use razor blades to clean the glass in your aquarium, then this is for you!

Simply place a standard razor blade between the two blade holders, ensuring the blade sits around the raised slot properly. Then place the holder directly in to the jaws part of the handle. Simple!

For safety when not using the scraper, you can turn the blade holder around and the exposed blade edge can be hidden away.

If you need a longer handle, simple print another handle part and screw it in to the existing handle. Easy! If the threads are a bit stiff, I recommend a few drops of water NOT any oils.
