This is a fully laser-cuttable edge-lit acrylic pendant. The battery can slide in its compartment to turn the pendant on/off.
Designed in Inkscape and cut on a Glowforge laser cutter.
This requires some hardware.
For the LED, I found a slow cycle animated rainbow water clear LED on ebay. You'll likely need to buy this part in qty. 100+
Laser cut instructions
This has three lasercut parts: the main body which should be cut from 3mm (1/8") cast clear acrylic and the two battery chamber parts, which should be cut from 1/16" black acrylic. See the associated SVG files.
For the cast clear acrylic, I used Glowforge's proofgrade medium clear acrylic material which is a cast acrylic that has paper on both sides. I removed the paper from the side being scored, but left the backing paper before cutting.
Cut settings (this is also the cut order):
Blue stroke: score (low-power cut, enough to mark the surface but not cut through)
Magenta stroke: cut first
Red stroke: cut second
The small notches that snap the battery into its two positions will likely need to be fine-tuned for your material and cutter. To do this, open Inkscape in the node editor mode and nudge them inwards/outwards.
Once all the parts are cut, polish the clear acrylic with isopropyl alcohol. Note: do NOT use extruded acrylic for this part; you will be very disappointed in the results and there will be crazing. You must use cast acrylic.
Please see the hardware diagram for instructions on where to place the various parts.
- Cut all laser cut parts and remove all paper backings
- Polish clear cast acrylic part with isopropyl alcohol to remove hazing
- Bend LED leads according to diagram
- Attach housing front (the part without the battery opening) to clear acrylic with screws, holding them together with your fingers
- Insert LED and then battery
- Attach housing back (the part with the battery opening) and put on nuts. Verify battery can slide before fully tightening nuts.
