Improved design for a printable razor scraper. I use this tool more than any other at the shop!

Print 100% infill.

Uses a standard Utility Knife blade and (1) #4 1/4" countersink screw.

Put the blade in place, then slide the retainer bracket down into place. It should lock in 3 different places: The back stop, the sides of the handle, and the sides of the blade guard. Pinch together tightly when everything is in place and then drive the screw in tight. The blade should be locked in place.

The rack pieces are sized to fit on standard 3030 extrusions.

Enjoy!
