This is a unique and original jigsaw puzzle designed by myself.
Based on a dodecagon tessellation pattern, the final design reminds me of miniature atomic size castles. This explains the name of my puzzle.
It is composed of 14 unique pieces that must be stored in the base using the tabs. The level of difficulty is about 8/10 (depending on your skill).
There are 3 different tolerances for the base, I added tolerance test files in order to know which version to print according to your printer (0.15 usually works well).
Size : Full puzzle with frame : 12.2cm x 12.2cm x 0.9cm (but you can print it bigger if you want)
The solution is given in a pdf file included.
