I see this and had to make one, it was then given to a little boy with SENd as a puzzle who loved this and made this in minutes, the cut file will fit and work nicely on an A4 sheet or 193mmx193mm 3mm Basswood PLY.
This was awesome and made some little lads Birthday and keeps asking my wife for me to make him more, so he can paint and hang them from his bedroom ceiling.
Something simple can make a huge difference
