Here is my method of removing stubborn prints from your 3D printer’s bed. This method does minimum damage to the bed coating (painter’s tape / capton tape).
All you need is box cutter. Follow 3 easy steps:
1 extend the box cutter blade and while keeping it at 10-20 degrees angle slide under the part with forward and side motion
2 retract the blade so the blade does not break on next step
3 with the blade inserted under the part, twist the box cutter until the part pops up
Works for me every time and keeps the painters tape in better shape compared to trying to pry it with a screwdriver or sharp object. Hope this helps someone.
