cccutter

This is a minimal credit card sized cutter with a safety razor blade inside it. It's only 2,5mm thick, so it should fit into your wallet. You can use it also as emergency seat belt cutter in your car. Works great for cutting wrapping paper too.

WARNING: This is NOT a toy! Razor blades are extremely sharp! Handle responsibly!

This model is designed to be printed in 0.2 layer hight with a 0.3 first layer. You have to pause the print after the 1.3mm layer (or at the beginning of the 1.5mm layer - depending on your slicer) and insert the razor blade.

I recommend fixing the blade with a drop of superglue to avoid displacing.
