Cat Dish Stabilizer

We have these glass cat dishes that came with an ugly base. Problem is, one of the cats doesn't like eating out of a wobbly dish so I made some stabilizers for them.

The inner ring is 39 mm, I uploaded the sketchup file so anyone can modify the basic design if they want. I printed it with my micro and PLA, low fill at 200 (works fine with no raft).
