Proof of Usefulness Score
Lab Mode

The project appears to be dormant or 'vaporware,' with no significant updates or evidence of active business operations since circa 2019. The submission contains demonstrably false and hyperbolic claims (e.g., 'most people have used my product', audience is 'everyone'), which act as major red flags. 'Marketcap' figure is unverified and misused in this context. No verifiable traction exists.

Description
Spül is the first IoT internet-enabled filament tracker, manager, and runout sensor developed for both 3D printing hobbyists and professionals. In a world that's printing bigger than ever, material management is key. Will this spool last through the rest of my 2-day print? How much material have I gone through so far? How much material is left in this print? I wonder if this spool is big enough to make it through... These are questions many of us ask ourselves almost every day. Being able to answer these questions will lead to better and more efficient 3D printing.
