Shelly DW2 18650 Case
thingiverse
This case was designed to use a 18650 battery in the Shelly DW2. The battery has charged 3.6V - 3.7V. Usually 2xCR123A in series have 3V + 3V = 6V. With the lower voltage, the Shelly is not overwhelmed and works cleanly down to around 2.9V. Then I would change the batteries. The Shelly has currently held for 3 weeks without restrictions. I used M3 VHB 4506 for the tape. It has ultimate adhesive power for many PLA things. If you also have enough 18650 batteries left and find the case useful, I would be happy about a small donation. This case may not be sold on other platforms or reused without authorization.
