This is a simple TPU straw cap and keeper for Stanley tumblers, or other straws with a nominal 10mm outside diameter. The inside is tapered slightly to result in a snug fit for straws of slightly varied diameter.

I have included 2 print profiles, one for use with either Overture HS TPU or Bambu HF TPU which prints very fast, and another for generic TPU.

I have also designed several models for decorative caps which can be printed in other materials or in multicolor and then glued on to this cap. Check them out in my profile.
