Bauhinia Megaminxed (curvy cut corner turning dodecahedron)
thingiverse
This puzzle is a functional clone of the MF8 Bauhinia Megaminxed. It's a deep and curvy cut, corner turning puzzle that shares similarities with the Starminx I in terms of corner turning, as well as the Rex Cube and Ivy Cube in terms of deep curvy cuts. Despite having a huge number of parts, including many tiny ones, this puzzle turns smoothly. Sometimes it can be a bit catchy, but this issue is usually resolved by aligning the moving parts more precisely.

For printing, my preferred technique is to split each piece into two halves, print them separately, and then glue the halves together. This allows for printing without supports, and such split pieces come with 'Split' in the file name. If you still prefer normal printing, I've added 'As Is' parts as well. For other print settings: 0.3mm or 0.4mm nozzle 0.1mm layer (0.2mm is also acceptable, but may require more sanding) 2-3 perimeters, 10-20% infill Cooling as needed No supports for 'split' version I recommend using ABS plastic because it's easy to sand. PLA and PETG will also work well, but they're much harder to sand. ABS can be glued with acetone, while PLA/PETG work well with dichloroethane. The core piece has a few througholes that are needed for precise positioning of the halves, as well as to improve inter-layer adhesion. Just glue pieces of filament into these holes. Printed and glued pieces will likely require some sanding to remove surface unevenness and glue seam. After that, outer pieces can be painted with spray paint. The final step is to cut stickers.
