Cube Lamp - Holocron Cover

What:

• Small Lamp using 16 (4x 4 LED Sections) WS2818B LEDs connected to ESP32 dev board and Holocron cover. The lamp is controlled through WLED and connected up to Alexa
• Notes: The Holocron cover doesn't always print great, depends on printer settings, but with a little clean up works just fine. There is some soldering work however but pretty straight forward.

How: 

• Printer: Elegoo Netptue 2S
• Nozzle: 0.4mm
• Modelling Software: Fusion 360
• Slicer: Cura Modified CHEP FF (0.28)
• Filament: Overture PLA Black 1.75MM and Eryone Clear 1.75MM
• Electronics: ESP32 Development Board, WS2812B LED Strip, M3 Screws, 22AWG Silicone Wire

Printing:

• I used clear filament for the diffuser channels, diffuser covers, mounting brackets, and lamp diffuser
• I used black for everything else

Installation (note: if really interested I could probably write more detailed instructions but here is the quick and dirty)

• Cut 4 strips of 4 LEDS to fit individually into each LED channel
• Solder the strips of LEDS together (about 2" wire length) and cover with heat shrink with nothing at the end and about 4-4.5" wire at the beginning (test regularly!!)
• Insert the strips into LED channels and slide on the diffuser covers
• Stand each of the 4 LED channels into the round mounting bracket with beginning cable coming out of center opening. 
• Attach the other mounting bracket to the top, optionally add the mounting bracket cover
• Inset the mounting bracket into lamp base feeding the cable through the hole
• Mount the ESP32 dev board to the ESP32 base using 2 m3 screws on the back. 
• Connect the wires to the VIN,GDN,D13 on ESP32 board (solder to the top or replace with 90 degree angled connector (e.g. JST)
• Screw in the lamp base to the ESP32 base using 4 m3 screws
• Put the diffuser cover on the lamp base
• Put the holocron cover on the lamp base over the diffuser
• Plug in the USB cable (note, I made sure to keep LEDS under limit for just a cheap USB plubg) 
• Go to install.wled.me and enjoy

Why:

• Another project with my boys. They have been having fun building lightsabers, 3D models, etc and I have been getting back into some basic electronics to keep me sane. They all seemed pretty keen on designing some custom lamps use 3D printing and LEDs. I wanted to create something that I could swap out covers for and the first cover is a Star Wars Holocron "inspired" design.
