Print one of these out of ABS at 100% fill to replace original teflon part that rounds out and prevents turntable from rotating. Why this part was molded from a plastic that creeps and only has a small D shape to rotate a large heavy platter is beyond me. Replaces Maytag R0130605 or Whirpool AP4246244              Just updated to have a slightly larger diameter D hole, as you can tell from the picture I had to manually open up the first one I printed to allow it to work.
