If you’ll be making the pendant using our design, let’s do the 3D printing first…then you can get a head start on the electronics while the printer’s working.

If making a votive candle or something else of your own design, you can skip ahead to the next page.

The 3D files for this project are hosted on Thingiverse. They’re tiny and should fit on any 3D printer.

Transparent or translucent PLA is recommended so the light can filter through. Do not use ABS filament for this project — it tends to shrink slightly and the space inside this case is already very tight.

Print each piece as a separate job (the results are cleaner, no stringing between parts) in high-quality mode with 25% infill. Clean up with files and/or sandpaper afterward. If you rinse off the sanding dust under a faucet, wait until the parts are completely dry before installing any electronics.

The file "spacer.stl" is only used temporarily during assembly and can be printed at normal or draft quality.

Test fit each part in the case before assembling or soldering anything. You may need to file away some cruft or even clip off one of the little board-supporting nubbins to ensure it all fits inside.
