PiWars 2019 - The Wheels
So … The plan today was to download a design for a Mecanum wheel, tweek it, and then print it. Unfortunately:
“The best-laid schemes o’ mice an ‘men Gang aft agley,”
Thingiverse has some lovely wheels.
I found the the first two are too small for our purposes. I’m also not mad on the central carrier/wheel hub idea. I liked the idea of using the parametric design and tweeking it for our purposes but Burns struck and I wasn’t able to open the SCAD files in Fusion 360.
So, like anyone would … I started from scratch, literally re-inventing the wheel. Fusion 360 is an amazing tool - I’d quite happily re-invent the wheel over and over. The main image is what I came up with. It took me about 1hr 30mins from blank page to fully rendered model.
I’ve decided to upload this to Thingiverse so anyone can have a go with it. I’ve also put up the Fusion 360 design files. I believe you can see the workflow of how it was modeled.

- Rotating view of exploded model
- Thiniverse link (in case you missed it)
- Video of a roller being printed (This was the only thing I had time to print tonight due to time spend modelling)
