Thule Chariot and Urban Glide cup holder adapter for the Bugaboo cup holder (https://www.bugaboo.com/us-en/accessories/holders-and-trays/bugaboo-cup-holder-MI001906.html). The adapter is designed to fit the Bugaboo cup holder, but can easily be modified to fit other models if needed.
I printed using black PETG from dasfilament (https://www.dasfilament.de/filament-spools/petg-1-75-mm/158/petg-filament-1-75-mm-schwarz?c=21), 0.2 mm Layer height, 30% Infill and enabling supports on build plate. Other settings/combinations will probably work fine as well
