This scraper can be safely used on the build plate with little danger of scratching or gouging the coating. This was inspired by a similar print by Tor G, but I decided to create a new 3D model. My design uses the same basic features as Tor G, but I widened and lengthened the handle. I also made it hollow with internal ribs, so even though it is bigger it uses about the same amount of filament and has about the same print time as the Tor G design.

See also Version 2 for an alternative design.

I should add that the Tor G design is very good and worth a look; I just enjoy creating my own models (and I need the practice!).

The OnShape 3D CAD file for this are available here:

Print instructions

Print flat side down with 0% infill. The internal structure is hollow, with three ribs to strengthen the blade (see the photos which show printing in progress). I rotated the print 45 degrees to get it to fit on the build plate.

I printed in PETG on a textured plate. It would probably work in PLA as well for many uses, as long as you keep it away from high temperatures.
