Ivy Cube

thingiverse

This is a functional clone of Ivy Cube. This is very simple, yet visually appealing twisty puzzle. Print settings: - 0.3 mm or 0.4 mm nozzle - 2-3 perimeters - 0.1 mm layer height (mine was printed with 0.2mm and surface is too uneven) - 10-20% infill - no supports - For outer corners, you may probably need model cooling as there are overhanging parts. Parts are split into two halves - this is necessary to avoid supports. Just print them and glue the halves together with acetone (for ABS) or dichloromethane (pretty much every type of filament). Perhaps printed parts will need some sanding. Here's a number of parts you'll need: - 1 Core - 4 inner spacers - 4 outer corners + 4 stubs for them - 6 center pieces Core parts have four throughholes - glue in a piece of filament. This will improve core strength (so that it won't crack by layers), as well as allow better positioning between halves. Springs are absolutely necessary for this puzzle, otherwise you'll not be able to assemble it. I used 0.5x5x10 springs I bought on Aliexpress, but springs from a clicked pen may also work well (though they may be too loose). Corner assembly is a little tricky. First screw corner stubs with M3x20 screws. Do not forget the springs. Do not tighten the screw too much - as per design there should be about 0.5mm between the core and corner stub. The spring should allow the stub to move up to 1-1.5mm from the core. You should set correct tensioning now - once the puzzle is assembled you will not be able to adjust it. Now glue outer corner pieces to the stubs using a few drips of hot glue. Assembling the rest of the puzzle should be straightforward. I used some shiny and unusual stickers, but traditional colors shall look great as well.
