I printed three of these on my Printrbot Play with Hatchbox PLA. The light blue translucent emitter was initially printed in ABS, but after multiple print failures I switched to translucent white PLA.
After painting my first successful print, I started making design changes to make it more printable. The first design change I made was to split the blue and silver components as separately printable parts. This reduced the amount of support structure needed. I further split the silver into two rings, four bars, and a cage, for the handle. The more pieces I used, the cleaner the final design. More pieces do require more gluing of parts in the end.
Recommend a Silver and Gold Sharpie, super glue, translucent white/clear or blue for the emitter, dark blue (tardis blue?) for the large components, and silver for the remaining parts.
