I made this spatula to lift objects off my print bed without damaging the bed surface. It has round edges to not cut into the surface and is thin enough to do the job. See Print Settings for optimal results.
Use 0.1mm layerheight for first- and all other layers to have it thin enough to slip between printed part and bed. Other settings:
Top/Bottom solid layers: 5
Vertical Shells: 4
Seam Position: rear (orientation as shown in the pictures of the finished print)
All Quality Settings in Slic3er except "avoid crossing perimeters"
