From the original:
No supports needed. Recommended to be printed in PETG or ABS for thermals.
Requires 4 m3 bolts to attach. Maybe some super glue between the parts if you want the extra hold.
I printed the top part with fuzzy skin to give it a bit of visual flavor.
(I'll get a photo with a better angle.)
The author remixed this model.
I liked the two-part design of the original model, but I wanted a base that was a bit squatter and wider. The drink holder in our car, also, doesn't friction hold cups in place. To make it a bit more stable, I added voids on the base so that ballast weight could be added. I used eight (8) 1/2in nuts as my weight, but other options are obviously available.
