Ideal for anyone who is car, van, bicycle or motorbike mad!!
I went for a typical car tyre tread style, and a typical motorbike style tread but you could go make one yourself that looks like a premium car tyre with curves and tapers, or you could go for a more minimal motorbike style - just google "tyre tread images" for inspiration!
Date Made: September 2013
Approx Cost: (Cost of printing?)
Approx Time: 1.5 hours modelling (plus printing time)
Step 1: The Model
This was done using tinkercad and can be found on their website by searching for "Wheel Ring" or here:
Step 2: Optimisation
Obviously this can be tailored to suit your size, or you might like to change the tread design.
There are plenty of different tyre designs out there, so play with the size to fit and play with the design to one that you like!
