FreeCAD project for a DIN rail case housing a Raspberry Pi Pico (W).
Features:
- M2 screw standoffs for the Pico
- two spots for two contact terminal blocks (I went for WJ126V-5.0-2P, other Phoenix PT-style should also work)
- three JST XH 3-pin connectors at the front for additional connections (these are soldered to a simple strip board and fit into the case)
- fully constrained
- partially parameterized
The case is heavily inspired by https://www.printables.com/model/1089412-esp32-din-rail-enclosure-rs485. I did lack the options to easily extend this and adapt it to my needs (in this project it houses a Pico W running ESPhome reading S0 pulses from an energy meter in addition to several water meters). And it was a good opportunity to get started in FreeCAD ;-)
