Small board. Small project. Still deserves a proper enclosure, not a zip-lock bag and a prayer. This 83 × 54 × 31mm grey jiffy box fits a vertical PCB up to 50 × 27mm or horizontal up to 62 × 49mm — that's the size of most hobby sensor boards and small amplifier modules. The lid underside has a 5mm centre-punch grid so your drill goes exactly where it should. A 10mm scribed-line grid handles any pass-through you need to file for a jack, a USB port, or a small relay. Base has its own punch-point grid for internal mounting. Screws are in the bag. Open, drop, close. You're back to actually building the thing instead of wrestling with a Dremel and a ruler
