James Williamson made this tutorial on making brackets for easily installable and removable NeoPixel strips using styrene. via intructables

I bought a strip of Adafruit’s RBG LEDs from Phenoptix. They come with a protective silicone sheath to stop moisture damaging them or metal shorting the pads. This is great but makes them pretty tricky to mount since it rules out tape or most glues.

I wanted a semi-permanent method to mount my LED strip. I could have 3d printed or bent some aluminium brackets, but ever since watching a YouTube video of Jimmy DiResta using styrene to make a box, I’ve found it hugely useful for making small items.

Styrene for enclosures and fixtures is a great material. It can be cut incredibly cleanly and easily with just a score of a knife followed by snapping along the score. It can be scraped, sanded, polished, painted and glued. Following Jimmy’s recommendation I use DCM as a solvent to dissolve two styrene surfaces, attaching them very strongly within several seconds. I’ve made joins with DCM and tried to separate them later, only for the Styrene to tear around the joint not at the joint.
