Bambu Labs X1-Carbon feet insert for 1.5" Sorbothane feet

Remodeled the 1.25" feet insert by @ToddFischer_601780 to have 1.5" diameter for use with X1-Carbon combo with AMS on top of the printer (which increases the weight to be outside the rating for smaller diameter feet at 50 durometer rating).

Since this is a remodeled version, the measurements are not exactly the same - that is entirely my fault. However, the version uploaded works for me in practice, even though it is a very tight fit (takes the entire weight of the printer to settle). I think this tight fit is probably good for avoiding vibrations, so I didn't bother to print a more exact version.
