Print instructions

Print in PLA using the 3mf files provided.

There are four sets of pieces :

• frame
• color B puzzle pieces
• color BA puzzle pieces (two colors with filament switching)
• color A puzzle pieces

I recommend printing in the order listed above. You can use two or three colors, but the puzzle pieces must be in two colors.

After printing the frame and the first set of pieces, check the fit before finishing the rest of the pieces. If necessary, you can adjust the piece size by scaling, although they should fit as is.
