I am sharing the Red Bull cup holder I made for my sister-in-law after she dumped over a can of Red Bull in her new car. This was designed specifically to fit a Nissan Altima, but should fix any cupholder that is at least 78mm in diameter. This should be 8.4oz and 12oz slim drink cans, but the smaller size cans will fit a little looser.

The picture shows an early attempt that I printed with the logo inset and painted in Bambu Studio. I didn't quite like how that turned out so I created a new version and brought the logo in line with the surface. I am also sharing the etched version for anybody who wants to paint (in slicer or after printing) or wants the logo inset on the surface, but left unpainted.

Since this is primarily intended for use in a vehicle I highly recommend ABS or ASA (or better). PETG may also work, but PLA could very likely have issues if left in a hot car. The bottom piece should be printed in TPU and glued to the main cup holder. This gives it a nice soft bottom. If there is enough interest I can upload a complete version without a separate, detached bottom.
