I modified the original design of the zeroPadsV6 to fit my leg size.
The gap is adjusted to a little over 4".
Instead of TPU, I decided to update the model to print with ABS/PETG.
I added additional holes so that they can be stuffed with yoga block or foam mat material cut to fit to provide crash protection.

Since this is the left leg version, you can mirror it during slicing to create the right leg version.

Since I provided the OpenScad & individual files, you can modify the design and share.
