Dual Digital Thermometer Case – Boiler/Heating Monitor (Flow & Return) 🌡️

A practical and compact enclosure for a digital panel thermometer with two independent wired probes.

My Use Case: I designed and used this enclosure in my basement for the central heating boiler system. The two probes allow me to simultaneously monitor the flow (feed) temperature and the return water temperature. It gives me total control over the heating system's efficiency at a single glance. It's also perfect for any other DIY electronics projects, server racks, or 3D printer enclosures.

The case features a dedicated slot for a side rocker switch and houses a 9V battery inside. The back cover is secured with M3 screws using heat-set inserts for maximum durability and easy battery replacement. Features ventilation holes
