KWOB // Grid

Rotate the two halves of this twisting KWOB and move the marbles along its shifting track to rearrange them until all like colors touch. Arrange with 11 balls total, 5 of color A, 5 of color B, and 1 of color C. KWOB has been designed for use with 14mm ABS or Acrylic no hole beads (actual diameter is ~13.6mm). This is one of my more simple twisty marble puzzles but a very satisfying one to play with!

Glue in 8 6mmx3mm (1/4"x1/8") neodymium magnets for a smooth and satisfying snap between positions. The magnets should fit snugly in the holes and you may need to use a flat surface to press fit the magnets flush. I also use E6000 craft adhesive to make sure the magnets are absolutely fixed in place. I like to use ABS filament for the clips for longevity, but I've also used PLA prints with no issues yet.

Add beads, then use the clip.stl to snap the two KWOB halves together to securely join the puzzle.

Default print settings:

• kwob.stl - 0.1 to 0.2mm layer height*, 4 perimeters/shells, 8 top/bottom layers, 10% infill (print 2)

Print settings are pretty lenient with this model. Adjust based on your own printers capabilities.
