one hour BLADE - Utility Knife

one hour BLADE

It's a tool that every maker needs. How many times you have taken a knife from your kitchen?

There are many version online for handling trapezoidal blade, but they too many complex and have many tolerance to pay attention. I have designed a simple version and it is designed to be printed fast.

It take only 22 minutes to print with a 0.6 mm nozzle, but I guess it can take less than one hour with a 0.4 mm nozzle too. No, I'm sure. Gcode for 0.4 mm nozzle is posted.

There are two version of the print. One has 4.25 mm holes where you can fit M3 threaded inserts and one with 3 mm holes where you can use only the screws. You can't use the 4.25 mm holes version using M4 screw because the blade won't fit.
