Pottery Trim Tower

It's made for a 12" wheel that is 1.2" thick on the outer edge, with 3/8" diameter pegs that are 10" apart on center. Print the two different lids for two different sized openings. CAD file is included if you want to try to monkey with it to make other sizes. I sized the openings to fit two fat orings that I found on Amazon. I took photos of the labels so you can see their specs. Note: Just added a third lid for bigger pieces. uses an oring that is 0.275" thick, 6.025" OD from Amazon.
