3x3 snake puzzle cube

I was looking through an old storage closet and found this snake cube. I think it is a really fun puzzle to play with and i hope you like it too. Pre-sliced files ready for a1, a1 mini, p1s, p1p, x1 and x1c. I have also included the original obj file from tinkercad. Boost MeBoost me for more puzzles and storage. Im new, but full of ideas. Please, give me more tips of what to design and publish next. To secure the string/rubber band, you will need strong glue to glue it in and/or a small(5mm-diameter of rubber band or string) size to lock it in place.
