Rubik's 2x2x2 hollow skeleton

thingiverse

A time before I have found photos of "minimal hexagon and heptagon" puzzles. I wanted to see how it works and start a series with a "triangle" puzzle. Because of problems I have stopped this project and will mark it as "failed project". I will share my experience with you 1. Photos of coloured thing: There is a unsymmetric dovetail connection between the elements. When move, it moves very good. There are not all the moves possible, so it is not a good puzzle. 2. Photos of brown plastic thing: There are symmetric dovetail tracks, this means there are connection elements needed. At corner points, very small corner elements are required. They will not be very precise, so very often there is a locking situation. In theory it works, in practical life there are problems. If work, it is like a 3x3x3 with hidden mid elements. Printed in ABS. Support required. Tracks to be cleaned very carefully, sanded, acetone vaporized. If you'll need a "minimal square" puzzle, look my "3x3x3 skeleton" here: https://www.thingiverse.com/thing:2271870
