I assume you're going to dye the snap-in (or are they to be glued) pieces?
My plan was to dye the tiles and then glue them in place.
Can they be removed once attached?
I haven't got one to test yet but I suspect that would depend on the amount and type of glue used. But yes I suspect you could pry them off again if you wanted to.
If they can be removed, with a Supercube kit you could make both ordinary style and supercube coloring schemes (and it would be truly an all-in-one kit
True. There are enough gears in this kit that you actually have enough to assemble two puzzles. The choice of gears used in the first really limits the options available to the second but I was thinking that would be a good way to store the parts.
As I said I haven't yet printed the Super Cube. The one I show here I had planned to copying the color pattern seen on the Ultimate Cube
. I'm still thinking about rather that is the best option. An idea that just came to me is I could use the flat area inside the center, yet outside the screw hole, and add 4 colored pegs. This would also give you center orientation information and the kit buyer would then have the option to assemble with or without the pegs. To me the Ultimate Cube's color pattern while it does give you a Super 3x3x3 can be confusing.
