This tool securely holds replaceable plastic and metal scraper blades. In addition to cleaning plastic or resin from 3D print beds, it can remove tape, stickers, dried residue, flaky paint or coatings, gaskets, … It is also great at scraping algae off aquarium glass.
There are several versions of the scraper to fit your specific needs. The standard version leaves 6 mm of the blade exposed, and the extended blade version leaves 9 mm (half) of the blade exposed.
The ergonomic handle version is the nicest to use, but requires supports. The simple handle (in the zip files) has a rod-shaped handle that comes in multiple lengths labeled by overall length, and prints without supports.

Instead of using a tool-less friction fit, I made a design that actively clamps the blade into place. As long as you have a matching blade size and reasonable printing tolerances, it should not come loose. If the blade is too thin and is not clamped securely, try adding thickness with tape.
There is a magnetic hanger for the ergonomic handle models. I made it to keep my scraper in a handy location on my tool cabinet. Glue the two magnets into place.
You can add fuzzy skin to give your handle sides a customized grip! Here are directions for PrusaSlicer:
You need to add supports when printing the ergonomic handle. The 3D model comes pre-oriented to minimize the amount of supports needed, and only overhangs less than 45 degrees need support. I recommend using the smallest Top contact Z distance that you can along with Snug supports for the best looking, flattest surface.
Please use common sense to avoid cutting yourself or other people. You will also need to consider the strength of a 3D print to avoid breaking the handle. The strength of your scraper varies greatly depending on your choice of filament, slicer settings, and printer tuning.
Thanks for visiting, and enjoy!
