Easy to print Places of Power based loosely on those in the Witcher 3 game. You can install electronic inside to make it glow, all you need is
- 5mm LED diode of your choice
resistor for that diode ( You can easly calculate the value here https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-led-series-resistor )
- 7x7mm switch
- 330 Ohm small potentiometer (to regulate the brightness of LED, you can use different value or don't use it at all if you don't want to regulate brightness)
- USB Micro socket on PCB
- Piece of PCB
- Cables
- Heat shrink sleeve
- And optionally a fuse (i added 0.8A quick fuse because i'm powering my from my PC)
You have to solder everything like in the photos and power up before installing to make sure everything is working.
Printing tips
Place of power can be printed in any filament you want, I printed mine with Creality Matte PLA (it's a great filament to paint) at 0.2mm layer height 2 perimeters and 12% infill. It's best to print the sign itself with transparent PETG for best effect. I also added some scale model foliage to make them more interesting looking.
Supports are only needed for first 3cm of the Place of Power due to electronic compartment,
