Some minimal plastic scraper blade handles. I have blades from Menards which differ slighty from the blades most scrapers are designed for. You can see an additional cutout in the profile picture below. So if your razor blades have those, then this should work! If they don't, then it should still work! There is a dimple which locates the blade in the center nicely.

Printing

• No supports required 
• PETG or PLA work fine
• Print in the orientation pictured below
• 4-5 walls & no inIl works. Feel free to try other settings.
• 0.3 layers are fine
• Brim isn't required
• ~ 30 min print for me
