Neat idea, but can you double check your stl version of the "light brown" chest piece? Your picture shows the chest broken up into 5 individual puzzle pieces, but in the provided STL, the chest section specifically is all just one big piece. And without the "cuts" for the pieces, the large chest piece doesn't quite fit flush into the corresponding base slot. The rest of the "light brown" pieces fit perfectly.
Thank you!
by the way, the revised print went great, and my kids enjoyed it on Xmas morning! Pretty easy to lose a piece or two, so good thing the pieces are easy to reprint! Thanks for the file!
