Ender 3 Raspberry Pi 3 Case Switch Version

Last crawled date: 4 years, 4 months ago

Hello,
I was looking for a Raspberry Pi case to mount it on my Ender 3 profiles and I came across the thing from 0711nimajneB (https://www.thingiverse.com/thing:3454663).
I had some switches laying around of my mechanical keyboard so I wanted to use the switch.
The switches are made to hold a 3mm LED.
The Button is connected to the Raspberry Pi. When you press the button, the Raspberry Pi shuts down and when you press it again, the Raspberry Pi wakes up.
The LED is a status LED to check if the Pi is on or off.
You need following materials for this:

Switch: (I used a Gateron Black, but I think any Cherry will work too since they are made to fit any keyboard PCB. (Check this before!!!))


LED 3mm: (I used a White 3.3V LED and a 220ohm resistor and the light is bright enough for me).


4x GPIO Jumpercables

Stuff for the soldering
Optional:

A stiffer spring for the switch: (Since keyboard switches are made for typing, the force to press the switch is pretty small. I used a spring from a ballpen and shorten it to the right lengh.

Keycap: (The switch works fine without a keycap, but you can use every kind of keycap).
The tutorials i used for this:
