This file helps you to not hit your fingers while hammering in a nail. It also helps you to hammer the nail in at 90 degrees to the wall/wood/...

There is also a 45 degree one coming out soon so stick around.

I did have some problems with extrusion as you can see but that's my printer's fault not model's.

3d print it easily with:

layer height 0.15-0.2

walls 0.6-0.8

top and bottom around 0.6

infill 5% and gyroid

support no

plate adhesion none or small brim

I suggest using adaptive layers in cura but it's not necessary
