So the feet on my Genesis 2 were lost to time. So I decided to whip up a quick model to replace them. I printed in 95a TPU, you can use any TPU you want. 100% infill worked, and 15% also worked. Depends on how stiff you want them. .2 layer height is fine, and TPU seems to like .2 better than .15 or .3 in my experience.
The author marked this model as their own original creation.
