Razor knife grip

I needed a grip to get a better hold of these razors to cut many cardboards. Its got quite an overhang at the back but printed "ok" with my ender 3.
Good enough for a tool.

I scaled it to 101% in all directions and 102% in width, as this was perfect for the razorblade and my printer.

Maybe you should print the first few layers and check if the razor fits through the gap. Its quite a snug fit.

Print it with the "blade" downwards.
I didn't need a brim but you might.

Printing:

2 walls, 30 % infill
Ender 3 60mm/s
0.20 Layer height

To get the razor in just press the handle onto the blade (see fotos)
To get it out you can just use the edge of your table and pull the handle downwards

Have fun with it
