Simple model, simple print, difficult puzzle. 14 pieces need to be printed in total. I printed the two center pieces red for cosmetics only. Having them in the center adds no difficulty as all pieces are printed exactly the same. I hope this puzzle is challenging to all that try. Enjoy!
I recommend printing the pieces at .2 resolution so theey stay more accurate. They came out fitting absolutely perfect for me with zero post print hand work. This puzzle is very solid when successfully assembled.
