This is a two part bass fish cap for your Stanley or other tumbler or cup. The part that covers the straw and is designed to be printed in flexible TPU (use the “StrawCapV3.3mf” file or print it directly from MakerWorld here: https://makerworld.com/en/models/488111#profileId-400979). Unfortunately Bambu Studio doesn't allow different nozzle sizes for the different plates in the same project, and TPU requires a 0.4mm nozzle, so that's why there's separate .3mf files.

The bass is designed to be printed in PLA or PETG with a 0.2mm nozzle. Once both pieces are printed, simply glue them together, and you've got yourself a fun and functional straw cap! I used Gorilla Clear Grip, but any glue that adheres to both PLA and TPU should work.

Check out my profile for other cap designs that fit the same TPU insert.
