Bambu Lab build plate scraper handle with replaceable blade
A comfortable scraper for lifting stubborn prints off a Bambu Lab X1C, P1S or A1 textured PEI plate, using a standard 100 mm plastic paint scraper blade or a stack of disposable safety razor blades. The handle is 140 mm long with a 30 mm palm swell, angled 20 degrees down so the blade meets the plate flat, and a 2 mm slot with two M3 screws clamps a blade of 0.5 to 1 mm thickness. The pointed tip helps under brims while the 40 mm wide edge clears large parts. Print it on its side in PETG with 5 perimeters; the shape has no overhangs.
The scraper in the Bambu box is small and its blade dulls fast. In SpeakCAD you set blade width and handle angle, preview it in the browser without paying, add a hex-key pocket in the chat, and download the STL.
Create a scraper handle 140 mm long with a 30 mm diameter palm swell tapering to a 40 mm wide by 8 mm thick blade head angled down 20 degrees, a 2 mm blade slot 15 mm deep with two M3 clamping screw holes 25 mm apart, and 2 mm rounded edges throughout.
