Mate Hood

This was a fun side-project a few months ago.

Especially v2 is not well tuned and should have more tolerances. I've kept it here for reference (and because of the nice twist with the bottom cap). v2 is a tight fit (69mm diameter) and tries to perfectly follow the shape of a 0.5 L Mate bottles. Unfortunatelly, due to the manufacturing process, some bottles may not fit or only under pressure. Further, the threads are not suitable for 3d printing. It's not terribly bad and you will get stringing, but still its good enough to work properly.

v8 is more mature (as you can see by the version number, there were quite some iterations). The cap is on top and very short. The idea was to put your name tag on the cap. I tried to reduce the print time on the name tag part. The threads have a 3d-printable 45-deg angle and a wider thread for faster screwing. Also, the diameter is slightly larger (71,5mm) to allow different bottles / brands. The handle has an unusal shape but in my experience it is nicer to hold. If you disagree, you can change the shape in the FreeCAD file.
