32oz Hydroflask adapter for 2016 VW Tiguan Cupholder.
I included a custom support from original model in 3mf with 0.2mm gap modified for: sparse infill, no top, and no perimeter (break away was trivially easy). Made in Polymaker ASA since it'll be staying in the car, so unfortunately got some warping at corners if anyone wants to improve supports. If I ever have to redo, will make three pieces with threads to avoid supports altogether.
The author marked this model as their own original creation.
