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. This Version 2 uses much less filament than my Version 1 and prints 30% faster, but is a little more flexible.

See also Version 1 for my first design with internal ribs.

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

Note added Oct. 5, 2021 : As some people have had problems printing this without infill, I have added files for 15% rectilinear infill.

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.
