3D printed magnetic scraper

[Cflow]

Wondering if anyone has made a 3D printed magnetic scraper that uses regular razor blades. Razors seem to clean much easier and a pack is just a few bucks.

I looked into making one. What held me back is that the blades I found always came with a oil on them. I didnt want to put that into my tank. If I could find some oil free blades, I would make one

Also wouldn't those blades rust quickly?

They do rust quickly, so maybe only use for occasional deep cleaning when the regular blades aren’t working.

The oil is keep them from corroding. Just wipe off using alcohol and you're good to go.
