The Answer.

Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.

This one : 42 Cylindrical Nest

Rotate the cylindrical pieces to scramble or unscramble.

Print instructions

Print in PLA using the 3mf files provided; otherwise :

• perimeters = 2
• infill 10% rectilinear
• top/bottom rectilinear
• no supports required
• no brim needed

I printed in all one color, two pieces at a time since I was testing the fit. No doubt all four pieces could be printed at one time, or you can print separately in different colors.
