PLA is great for this despite being brittle and not as flexible as PETG.
Try the original size (100%) and if its too loose, print it in 2% increments (102%, 104%, etc..) or vice versa for too tight. It should be able to pop just right without rotating. It's impossible to have a universal just-right size because of the variation of shrinkage from different brands, even for the same material
Added grip to the thumb stick so it isn't as slippery when playing video games. Just like the original model, no glue is required to have it stuck in place without spinning.
