Colorbeam base

This colorbeam LED board is specifically designed to hold the board: https://www.tindie.com/products/ColorBeam/colorbeam It perfectly centers the LED in place. Illuminating your projects has never been neater. I used a "Noctural Mystra" (http://www.thingiverse.com/thing:398413) in the photo. The Colorbeam boasts an entrancing movement between colors, rather than any distracting blinking or flashing effect. Instructions To mount the PCB securely, align it using the 3 holes on the board. Two pegs will fit snugly into two of the holes at one end, and a single hole at the base next to the connector serves as the anchor point. To reinforce this attachment, I have drilled and tapped for a #2-56 screw size (alternatively, a 2mm screw would also work; however, use no larger screws than that). If desired, create a peg or employ hot glue as an alternative bonding method. During printing, I used 0.2 mm layer height with a 50% fill setting. Three perimeters yielded satisfactory results, but using two should be perfectly fine if you choose not to drill and tap holes for the screw attachments.
