Kong drying station for laundry tub

My dog has too many Kongs and I always was running out of space in the sink when I wanted to dry them after washing.
This Kong drying station is for medium sized Kongs (3.5-inches long).

March 4, 2018 Update: I added a design for large Kongs (4-inch tall). Since they are quite a bit heavier than medium-sized Kongs, I added a 2nd support for stability.

I usually have to scale by 10 all my drawings when they go into my slicer. It maybe because I draw them in mm and slicers may expect cm.
