Pot lid rack

thingiverse

Here are the parts to a system that allows you to adust the depth in 5mm imcrements by printing more spacers which stack together snugly for a perfect fit. Here I've used 3 different depths to accommodate the various pot lids I wanted to store. Of course hooks can be added, it can be a towel rack or whatever you want. In this case I took advantage of some unused space. The metal bar I used and it was designed for is common inexpensive 1/2" conduit from the hardware store but I'm sure many other things would work just fine.
