Photographic Estate Dimensional Analysis

Estate photographs were used in conjunction with a pair of calipers. Screen was adjusted until a common reference point was ascertained. The reference point used was the known dimensions of the LED PCB width, being 1.00". Length was determined by laying out the number of 5mm LEDs (16-qty) in a PCB CAD software. The distance from the first to the last was exactly 4.00". When the screw terminal via holes are added, the board length becomes 4.75" long. This is what decided the length of the acrylic body.

BODY:

Acrylic "photon injection" length: 4.75"

Acrylic "photon injection" diameter: 2.75"  (note that flat spots were intentionally done on the 3D prints to allow for LED PCBs. It was found that a square of equal sides, 2.75" with .875" radius on each corner produced the desired outer diameter and provided 1" wide flat surfaces for PCB mounting). A 0.375" depth was chosen based off dimensions of 5mm LEDs for the grooved portion.
