D1 Mini ESP32 DIN Rail Case with RS485 & Oled

thingiverse

This is a remix of the D1 Mini DIN Rail Case 1TE, RS485 by https://www.thingiverse.com/thing:3337686. This one was created for the Sofar2mqtt project but may be useful in other scenarios too. (if using with ESP32, use my fork here: https://github.com/ASMotionLab/Sofar2mqtt) Modifications: - Enlarged width to accept a 0.96" i2c oled display and to accommodate dupont wires. - Slightly resized footprint to accept the D1 ESP32 module (which is bigger than the 8266 version) - it sticks out about 3mm more. - The MAX485/MAX3485 board has moved to the back, so now fits only without the screw terminals. - The small clips on the lid have been slightly reinforced with a small bevel. - Added 0.2mm (approx) clearance between lid and back of the case for a slightly better fit. - USB port hole moved slightly for better alignment with the port. I found that the clip retainer bar wasn't needed - PETG is a slightly 'sticky' material, so the clip is retained by friction. Notes: - Check your local rules to see what material is allowed inside your wiring cabinets. Hydroscopic materials like PETG may not be allowed. - The soldered pins on the Oled display may need to be trimmed/pulled back slighly so they don't protrude past the front of the PCB too much, otherwise It'll be tricky to slide the display into the slots. - You may or may not need to use a pin to retain the DIN clip and stop it from falling out. Depends on how tight your slicer's tolerances are dialled in. I found that it's a very snug fit and it's retained just by friction.
