As my electrical longboard has hard wheels and i wanted to soften them a little bit i created an adon for 90mm wheels.
I have not tested them while driving so far because of winter so i can not say if they do the job as they should.
I printed them with Ninjatek Flexible material witout any supports or problems during the print.
it is a friction fit so they are a little bit hard to put on which is hopefully a good thing.
There are (for now) three kinds of wheels uploaded.
one without any profile, and two with profiles. The ones with profile are mirrored in extra files (wheel-profile-1-x, and wheel-profile-2-x)
