Who doesnât need these?!

Had to stop my print. These hands will be great but the model has undulations at the base of the supports. Examples: The Flat hand model has inadequate supports that rise up at the ends of the rings such that the first layer wonât be on the print bed! The pointer is much worse. The very end of the support ring dips lower than the rest of the ring so none of it sits on the bed. The first layer would print into thin air, which is a shame when this is supposed to be the support that prevents that from happening. The ball socket is floating half a mm above the bed before the first layer.
To remedy, I had to bring the pointers into Tinkercad and slice away the bottom up to the ball joint, then I had to add some material under undulation in the rings. For the flat palm, I had to lower the entire model into the print bed so it is sinking about .2mm so it has a good first layer. That shaved off a little of the ball joint, but I think it will be OK.
Author, these are cool hands. Please take another look at them and fix the support rings.
@caver01_122051 sorry for any troubles you had with my model. This is possible, because I just rigged the original hand in blender. I didn't have any problems with printing all of my hands, so I supposed it was good enough.
Same issue, was scratching my head trying to work it out until I saw "overhang perimeter" in prusaslicer. (edited)
