These are 4 basic pieces that can be situated to hold just about any size of pot lid. If you just have 1 lid, just print two of the first piece. If you have 2 or more, just print 2 of the first piece and n-1 of the second piece (e.g. if you have 5 lids print 4 of the second piece). If you need to stack lids, print the last two pieces (stacked lids should be about 1" different in diameter size)
Print with 3 perimeters and any infill. Example is printed in PLA, but PET and many other materials would also work. Some supports are needed for the screw holes, and screws are needed to attach the pieces to the cabinet.
