Parametric Table Leg Stabilizer Pucks

I had a wobbly wire shelf (well, my floor is uneven), and also sometimes when we visit restaurants the tables are wobbly. I wanted something customizable. Here it is. The picture in brown - i printed that with fuzzy skin (its a slightly older version of the code). 50% infill with cubic(?) infill for strength. The disks it prints are stackable to get various other height adjustments, default 1mm-7mm in 3 disks.
