I printed in PETG. It seems to be a fraction of a millimeter too tight when I use real pennies. The printed ones worked fine.

The only thing I didn’t like was having to print a whole layer in a different color to get the text that color. Not a huge deal though as that one layer is not too noticeable on the sides.

This is a terrific print! Thanks so much. In the slicer I added 0.1mm to the XY hole compensation setting which allows for real pennies to fit much better while still being a challenge. I've added my print profile for others to use if they prefer real pennies. I didn't include the solution in my photos to avoid spoiling it for anyone.

Your board is too small. I used the example shown and the coins will not fit.

regular pennies didn’t fit

printed good but its much easier than in videos i have seen the coins might need to be just a little bit bigger because when solved there still much space

just shy of working with real pennies, and way too easy to complete. not sure if it printed correctly or if this is meant for very young children

Thank you!

I was hoping that someone already made this. Will upload a make asap
