Drink holder with large diameter base

I wanted a drink holder that could be used on our boat or out sitting in the yard or just sitting at home on the carpet. I designed the two pieces in TinkerCAD.
I printed mine using PLA filament.

This is the Stainless Steel cup holder that I bought from Amazon for $7. There's a little foam strip under the edge that you will remove.

(Note: I believe I fixed the link. The Amarine drink holders are sold in various quantities from Amazon. If you want to buy more than one, you may want to look for the 2 or 4 pack.)

Use supports when printing the Base. It only needs it in the very center, but will be obvious why when you look at the design.
