Koken 3/8 metric socket set Gridfinity

This is a Socket organizer for the Koken 3/8 Metric socket set with part no: 3210M-05. It is just for the sockets and the universal joint, not the other things in the set. This is my first ever sketch, so I am sure there are ways to improve it :) It is buildt based on Akio-42's Gridfinity tiles and I used the 3x5 tile as base.
