A scraper using simple razor blades which is not flimsy or imprecise. The blade is held firmly in place.
Please be careful when inserting the blade.

Use razor blades such as this one: https://www.amazon.de/P-G-ASTRA01-Astra-Rasierklingen/dp/B001QY8QXM/
EDIT 2020-06-26: Made it a tiny bit wider to make replacing the blade as easy as pie.
No support needed, I used variable layer height to make the slope smooth.
