Josip, these are amazing. Well done. I only wish that such a thing were available for the long boards as well or that I had even a tiny bit of the skill needed to 3D model such a thing.
Thank You Tood :) Yes, I should try to make a version for long boards; because they are less reliable so it will make more sense. I'm no expert in 3D modelling, just a little practice and a large number of tries :) ha ha ha
