SOLIDWORKS Design & Help

Created by Angel Ramirez on 9 March, 2018

Hi guys,

I have a problem with a design of a Japanese wooden puzzle called "Double Kumiki Puzzle". It's made up of 12 interlocking parts (9 with 2 cutouts and 3 with 3 cutouts).

This video could help:

I just cannot find the cutout's tilting angle.

Note that it's something near 20 degrees.
