Slide-Together Structure

Puzzle description:
This is a small version of a sliding structure consisting of six identical pieces. It was designed by Rinus Roelofs (http://www.rinusroelofs.nl/) and is presented here with his kind permission.
With the six pieces you can build two different symmetric structures. A larger version and an additional table top gives a nice coffee table (https://praktrik.com/1x6).

Puzzle difficulty:
Easy, but interesting. The problem is that you cannot slide in all the six pieces one after another. Good for beginners.

Printing instructions:
Print six identical pieces. For different printers, a tight and a loose version with different tolerances are provided.

Prints are fine with no supports.
I printed the puzzle in PLA at 0.1 mm layer height.
