Free lens focus ring generator replaces overpriced pro gear; tiny but delightful.
Photographers, filmmakers, 3D printing hobbyists

Free to use and easy to share.
The exported STL will show open manifolds on the slicer, but it will print fine.
I also want to make an open source follow focus mechanism (both manual and automated) to go along with it.
Thank you for trying it and I'm happy to hear what you think!
The review zeroes in on what actually changed: recessed sensors, titanium comfort, and an 18-pathway Smart Sensing platform that promises better sleep and HRV data. It calls out useful features like automatic activity detection and 30+ tracked metrics, but glosses over the usual purchase blockers — battery life, subscription pricing, long-term accuracy, and data/privacy tradeoffs.
Fills a gap Oura's app left, but it's a widget wrapper with no novel mechanics.
Smart e-ink health dashboard, but you need both an Ultrahuman Ring AND a TRMNL device.
MCP wrapper around Oura's existing API when direct API calls work just as well.
Local SQLite mirror lets Claude analyze Oura trends and log context like alcohol or travel instantly.
Two-slot ring buffer cuts MLP RAM usage to the practical lower bound on microcontrollers.
