This is used as a pad for a Daytona jack. Measure the top of your jack as it doesn't work with my other jacks. Just wanted something better than a 2"x4" and this fits nice and snug. I used PETG at first but that dented poorly from the differential, so switched to TPU using PETG settings with my mini. I did 50% infill, it works fine but lost all its rubbery properties. Not sure if I'd scale that down or not but works great for my purposes!
