One of the first things I ever drew in 3D. Happy to share it with you.

Print 6 of the Long, 15 of the Short, and 3 of the Key

These will assemble with a repeating pattern with 2 long pieces at the center, and the short pieces holding each long assembly.

Long pieces will thread through each other in the center.

A key will be needed as the final part on each of the 3 axes.

Have fun.

Notes:

These should come out a bit tight as is needed to hold them together. You may need to adjust down the HORIZONTAL EXPANSION to get a more loose fit if you prefer.
