Starminx I (Corner turning dodecahedron)

This thing is a functional clone of MF8 Startminx I puzzle. This is a corner turning puzzle, technically similar to a Dino Cube, but in a dodecahedron shape. Despite number of pieces this is a pretty simple puzzle to solve, can recommend this for beginners.

Number of parts to print:

1 Core
12 Centers
30 Edges
20 Corners

You will also need 12x 0.5x4x10 springs (can be bought on aliexpress) and 12x of M3x20 screws with a small head. Springs are recommended, but not really mandatory for this puzzle.

I was pretty lazy to design center caps for this puzzle (as original one has). Center hole is just covered with a sticker, and this still looks ok. Though you are welcome to improve this design with a capped center piece, onshape source is here.

As for printing. My favorite technique is to split each pieces into 2 halves, print them separately, and then glue halves together. This allows printing without supports. Such split pieces come with 'Split' infix in the file name. If you still prefer normal printing - I added 'As Is' parts as well.

As for other print settings:

0.3mm or 0.4mm nozzle
0.1mm layer (0.2mm is also ok, but will probably require more sanding)
2-3 perimeters, 10-20% infill
cooling as needed
no supports for 'split' version

I recommend ABS plastic as it is easy to sand. PLA and PETG will also work well, but they are way more harder to sand. ABS can be glued with acethone, PLA/PETG work well with dychlorethane.

Core halves have a few througholes. They are needed for precise positioning of the halves. You can just glue pieces of filament there to be sure about the positioning.

Printed/glued pieces will probably require some sanding to remove surface unevennes and glue seam. After that outer pieces can be painted with a spray paint. Final thing to do is cut stickers.
