Wemos D1 Mini Light switch servo mount compatibility version w/ limit switch

thingiverse

This is a remix of the remix by sfarzosoitaliano. This version increases clearance and length for the servo arm for increased compatibility and adds some mounting holes and a mounting plate for a limit switch on the servo arm. This can be used to determine the position of the switch if it was manually toggled rather than being actuated by the servo. Print this servo arm if the original one doesn't fit or if you want to add a limit switch to your design. ============= I really, really dig the light switch mount plate for an SG90 servo to activate a light switch. I have a bunch of smart bulbs for my other lights, but my kitchen lights are the long, giant, bright bulbs. Phillips' Hues don't really come in that size ;) So I wanted to activate the servo with MQTT (from a RPi running Home Assistant and Mosquitto MQTT server) using a Wemos D1 Mini. I know you're generally supposed to power servos from their own power supply and not the boards, but I figure quick activation are fine. Plus the 5V may be straight from the USB before the regulator for the Wemos D1 Mini, I need to look into it. Regardless, it should be fine. I took the D1 mini case file and combined it with the plate. The thing is not heavy at all, my light switch screws don't even feel the burden. Then I modded the case lid to make room to hide all the wires from the servo and D1 Mini. I also had to trim the press fit sections to be a bit smaller, and the GPIO holes to be a bit wider/longer. Quick to activate, low cost (already had the servo from a starter kit, bought a bunch of D1 Minis and we all have 3d printers, right?) this thing is awesome. I ran out of white filament on the unmodded versions though... sadface. I included the arduino sketch I used to program the Wemos, and the solidworks file for the lid. Enjoy!
