Airglow

A parametric lamp design using WS2812B / Neopixels LEDs and a NodeMCU v3.

Printing Instructions

Before you print anything, make sure your parts' dimensions fit together. Since

this design is compatible with a whole variety of lampshades, be aware that some

lampshades will have to be scaled down or up to fit the base's default settings.

Base

- Layer height: up to 0.3mm is fine, there's little detail on the Z-axis

- Seam: Rear (hidden on the back of the lamp, along with the USB port)

- Infill: 5% would be enough, 10 or 15% is recommended for cleaner prints

Cover

- Layer height: up to 0.3mm is fine, there's little detail on the Z-axis

- Seam: Rear (hidden on the back of the lamp, along with the USB port)

- Infill: 5% would be enough, 10 or 15% is recommended for cleaner prints

LED Strip Holder

 Print this part in vase/spiral mode!

- Layer height: use the biggest layer height your printer can handle

- Bottom layers: 0

- Infill: 0% as it's printed in spiral mode

Diffuser

 Print this part in vase/spiral mode!

- Layer height: use the biggest layer height your printer can handle

- Bottom layers: 2

- Infill: 0% as it's printed in spiral mode

Lampshades

 Print this part in vase/spiral mode!

- Layer height: depends on the model and size of the lampshade

- Bottom layers: 2

- Infill: 0% as it's printed in spiral mode

Assembly

Stick the LED strips into the strip holder's channels. Note that each segment

has a direction (indicated by an arrow printed on it). Route them in a zig-zag

fashion: first segment points upwards, second segment downwards, third one

upwards again, and so on. The WS2812 strips can be powered from either end, just

make sure you match the polarity indicated on the strips. Connect each DI pin

with the DO pin of the segment next to it. The first segment's DI pin gets

connected to the micro controller.

The NodeMCU v3 has a VUSB pin, which you can use to supply the strips with 5V,

directly from its USB port.

Software

Use WLED! Make sure you set up multiple segments, with their `Reverse Direction`

setting enabled alternating. Configure the maximum power draw to match your

power supply's rating. Store a preset with your favorite effect and colors, and

enable it to be the default on boot-up.

Notes

This design was heavily inspired by BRUXXUS's amazing Chromalux design, and is

even compatible with some of its components, like the lampshades. The reason I

decided to come up with my own design, is that I wanted to make a parametric and

free design that can be customized to fit any LED strip, micro-controller, or

lampshade, and can be scaled up or down as desired (or as required by your

printer's dimensions). It also improves on the original design idea in various

ways, allowing for a tighter fit of the components.
