I looked at upgrading my scooter wheels with pneumatic ones to improve the ride, however, there were no options, and randomly buying scooter wheels wasn't a sensible solution. So, I ordered two pneumatic hand cart wheels for £10... then set about making a sleeve with a keyway that I could bond into the bearing sleeve on the new wheels. So the existing axles could drive them.
The concept of using 3D printed parts with steel parts was an idea that was born from seeing successful use of 3D printed press tooling in the aircraft industry (On Hackaday).
This setup was tested today, by driving around an auto jumble. It did not fail... All I got was some strange looks at the non standard wheels.
Thank you Hackaday people, you're awesome!
Just updated the wheels to better (red) ones I found at my local B&Q DIY store.. The original metal ones were a bit buckled.
Enjoy this project?
