Edge Lit LED Engravings

The material used is 3/8" cast acrylic from an unknown manufacturer.  Other plastics may also work but cast cuts nicely and the  thicker material adds visual depth.

The dxf file can be found here:

The cutting file was created in Fusion 360.  The original dxf file was edited to  contour around the top of the car.  The contour was cut with a 1/4" 2 flute end mill. The etching was done with a 'trace' toolpath using a 90 degree v-bit cutter at 0.012" depth.  A depth of 0.006" or 0.008" would have created finer detail making tidier work of the CAMARO text.  Notice the text (and the car) are a mirror image because the engraving is on the 'back side',  or in other words the display side is an uncut surface.

The Lotus Bloom engraving was a test cut.  It's the top of a laminar fountain nozzle which may be described in a future blog entry.

The LED lights are cut off a spool of strip lighting commonly found on EBay or Amazon.  A two section piece can be seen in front of the Camaro in the photo below.

Bad photo background,  what looks like dirt or scratches is really the dust shoe brush on my router.  The power is supplied by a 12V wall wart.  The 4 position switch was salvaged from a multi-function flashlight.  The colors available with this switch are red, green and white. (Is white a color?).
