If you cinema a lot this may be of use. I find it a challenge to carry the large refillable cups and popcorn along with coats and other stuff when I visit the theatre. Adding the Regal branding is just a tiny level up but it's easy to delete the text and modifiers if you want a plain carrier.

This is based on the Reusable collapsible coffee carrier model by danielwould on thingiverse but is completely redesigned for ease of print and to hold much larger cups.

I printed this in black PLA with a gold silk PLA for the Regal branding. The logos and font are not exact but fairly close approximations I made for fun.
