Green Lanterns Build Guide

Prepare the wires

Trim the mode/power switch wire down to approx. 6 cm and strip the ends.

Find the 3 cm length of black/red wire and strip the ends.

From left to right, solder the battery connector (in-line socket), the black/red wires for the USB‑C charger, and the mode/power switch.

Align the battery cable with the hole at the base of the insert, and attach the panel with a piece of sticky tape.

Insert the battery cable into the hole and up into the centre of the insert.

Thread the USB‑C power connector wire through the hole in the base, and solder on the USB‑C connector.

Use a small amount of glue to stick the panel to the tube of the insert along its edge.

Use a little bit of hot glue to insulate and secure the soldered terminals.

While the glue is hot at the bottom, wrap the rest of the LED panel around and glue it along its edge.

Wait for it to cool and solidify.

Don't overdo the glue Too much hot glue can melt the PLA plastic. PETG would resist the heat better — but it's a bit late for that now!

Again, glue in the button — but don't go crazy with the hot glue. Use a bit and let it cool down.

Solder the battery connector cable to the battery carefully.

Check polarity Observe the polarity — red is positive (+), black is negative (–).

first power-on

Connect the battery to the inline socket — the LEDs should light up! Carefully drop the battery down into the centre of the LED insert.

Try the mode button.

Push it in until it's flush, with the wire gap aligned with the gap in the edge of the frame.

Pick a blank panel, or a printed pattern, and decorate and customise it as much as you'd like.

Use the MagFit clips to attach the spacer (it looks like the base, but flat).

Again with MagFit clips, attach the ring at the top — and a skirt on the bottom.

final step

Now the glue has cooled and dried, insert the module into the base and twist it to lock it in.
