Print in TPU
Use .2mm layer height
Use 10% infill - enough to add a little structure but still want it to be somewhat squishy - I printed in 95A hardness (which is pretty stiff, squishier TPU may need a little more structure, but I think 10% is good for most).
Use a TPU specific profile to slow down printing an appropriate amount
Note: Printing with 1 perimeter will make this feel much ‘squishier’ but it may not hold up as long. I've found that either 2 or 1 perimeter are functional but 2 may hold up longer.
NOTE:
While this was *not* remixed, my model was inspired by this other thingiverse object that I want to give some credit to: https://www.thingiverse.com/thing:5258887
I modeled this from scratch in Fusion 360 because I needed something smaller and needed to tweak a couple of profiles. Lastly, I wanted to try and build it using parameters so I can resize easier in the future. So, while this technically is *not* remixed, it is inspired from the work done by this person - thank you!
The author marked this model as their own original creation.
