PATH Water Bottle Cap

Replacement Cap for PATH 25oz Aluminum Water Bottle
A two-part replacement cap for the PATH 25 oz aluminum water bottle. The PLA outer cap handles the threading and structure; a TPU 95A solid disk gasket drops into the inside to seal it watertight. Tested on inverted bottle, full of water — no leaks. I am a huge fan of the PATH water bottles and couldn't find a replacement lid out there, so decided to make one and post it here.

**Bottle compatibility**
Designed specifically for PATH 25 oz aluminum bottles, but should fit any bottle with these external thread specs:

Major diameter: 37 mm
Minor diameter: 36 mm
Pitch: 3 mm
Single start, right-handed
10 mm threaded length
28 mm mouth ID
34 mm OD smooth rim above threads
41.5 mm OD shoulder flange
If your bottle measures the same, this will fit. Worth checking with calipers before printing.
