RC model plane wheel centre

I needed larger wheels for an RC plane (smaller ones kept digging in) so made these.

So clean up the parts and glue one rim onto the centre, make your tyre to fit then lock it in place by gluing on the other rim. You can achieve various offsets doing this. Assembled weight at 100% infill PLA is 8g

Glue tyre in place if you want to, once assembled any tyre wear / damage and you may as well print a new one but could squeeze and glue another foam tyre over it. Tried to make it like a car wheel in that sense.

I have included the Freecad files so anyone with this can alter it. To change sizes you can just use a slicer. As an example wheel can be m
