Router plane designed for 3d-printing.
All you need is a 10 mm allen key thas is ground down to the profile you see on picture picture 2, and a 8 mm bolt.
I recommend printing the bottom layer at least 2 mm to prevent warping.
The hole for bolt is 7 mm so that you can heat up an m8 bolt slightly and screw it in, or tap a thread.
printed with normal support and 30% infill
