Snake puzzle

I made this puzzle because my 5 year old kid was very disappointed when his snake puzzle slapped. Draw this from tinkercad just to show him how easy we can create one of those from 3D printing. This version have quite high tolerances for my beginner 3D printer - creality ender 3. I used different eSun PLA+ for testing. The slap on part work fine with the hole most of the time if you print them at the same lot.
