Multicube (functional clone)

This is a functional clone of Greg's Multicube produced by Yuxin. I never printed this particular puzzle as I already have one mass produced. I just wanted to prectice in designing puzzles like this. So please let me know how does it work.

Original CAD document is here: https://cad.onshape.com/documents/8d39382def9ea2b727dfd829/w/807544f66a276a0647e1ef04/e/b30bc048b070826f52129c17

Printing recommendations:

• 0.3 or 0.4 mm nozzle
• 0.1 mm layer high (0.2 mm should work as well, but higher layer height will lead to uneven surface)
• 2-3 perimeters, 10-20% infill

There are 2 versions of parts: split and non-split. Non-split ones are pars as is. You will probably need supports to print them. Split version does not require support, but each part is printed as 2 halves that need to be glued together (I would use acethone for ABS, and dichormethane for PLA and PETG)

Here is number of parts needed:

• 1 core
• 6 inner centers
• 6 outer centers
• 8 inner cores
• 8 outer corners
• 12 outer edges
• 24 center edges

To assemble the puzzle you'll need 6 pcs M3x20 screws, and 6 pcs 0.5x5x10 springs (search of aliexpress)
