Flux Capacitor Cover for LED Strip

A Flux Capacitor themed cover for the WS2812B addressable RGB LED strip sized for the 30 LED/m variant. The section of LED strip encased in the part should be 10x33 mm with one LED behind it. You can secure the strip inside with a thin piece of double-sided tape. It diffuses the light coming out into the flux capacitor shape and can be used as a mini-scale prop. The two parts are a snap fit with detents. You will need a multi-material capable printer to print this or manually do the colour changes for the first couple layers (it's not too long or unbearable and this is what I did instead of using a multi-material system).

Use 0.2 mm layer heights and import the step files into your slicer. You will need to split the diffuser into its two bodies in order to make the centre "Y" shape in clear PLA all the way through. For the other parts, they are just ever so slightly offset in the CAD from each other on the same body so you can simply select them as different faces and paint them with the corresponding colours (see the picture for reference). You can use PLA for everything and will need clear, red, gold, silver, black, and a blue-grey (for the inside-rear of the window). Print both parts with the flat sides down (so the design will be on the first layer) and that way nothing needs support.

You can then program the LED with a controller of your choice to flash a blueish-white and flicker to mimic the flux capacitor. The rear mount can be secured to whatever you want with double-sided tape or superglue.
