Description
With this adapter you can equip a MagLite 3D with 2x18650 Lithium batteries instead of 3xLR20.
You need to also change the bulb, as the voltage will be higher with up to 8.4V.
There are plenty of B13.5S LED bulbs available.
Optionally you can add an BMS and USB-C charger, see last picture for schematic.
BOM:
- M3 screws, nuts and washers for battery connection points
- 4xM2 screws to mount the end-cap
- spring, i used one out of a old hole puncher, see photos for dimensions
- a few cm wire
- optional: 2S-BMS
- optional: USB-C Charger
- optional: 3 cable lugs, you could also solder the wires directly

Hey, as a starting point see my 2D conversion https://makerworld.com/en/models/180585#profileId-198714 last picture shows a schematics. For the 3D you just have to add the 2s-BMS.

Could you please add such a schematic for the 3D version, im a bit confused about this picture (https://makerworld.bblmw.com/makerworld/model/DSM00000000113286/design/2024-01-05_f444fb0ab5653.jpg?x-oss-process=image/resize,w_1000/format,webp) it looks like the minus pole on the other side compared with the schematics of the 2D.
Thank You
