LEGO® compatible tire 3483 replacement

This is the matching tire #3483 that fits the LEGO® [3482 hub](https://www.thingiverse.com/thing:2085115), both of which are no longer in production. I made this primarily on request, but also just because modelling it was fun. The Blender source file is included for those who want to know how I model something like this.

This was modeled from the actual part by measuring and eyeballing, so don't use this as a reference for the exact measurements of the real part. However, my test print fits pretty nicely. I also included the mysterious asymmetrically positioned inner ring like in the original part, if anyone has a clue why this is there, I'd like to know!

Obviously, this must be printed in a flexible filament to be of any use. I printed it in rigid.ink flexible PLA which is a bit too stiff for the task. Although it is possible to fit the tire around the rim, it doesn't have much grip. NinjaFlex or a soft TPU would be a much better choice (but I don't have any at the moment).
