A convenient hook for the horizontal metal bar on Thule Chariot and Urban Glide strollers (might also fit other models). Useful for helmets, jackets, bags, toys etc. The hook snaps securely onto the bar.

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 and Infill at 30%. Other settings/combinations will probably work fine as well
