A few months ago several of you purchased my RGB LED flipper button kits for your games. One feedback I received from a few users is that they wished they were brighter. The idea was maybe if the metal flipper button nut could be replaced with a clear one. Well, those aren't available anywhere I can find, but I have been testing several ideas with 3D printed versions. The best option I tested was to use clear PLA (prints translucent, not clear) to 3D print a much narrower nut that doesn't block the light. I ended up finding that a 1.5mm thick nut does the job quite well and produces the best improvement.
While there is definitely a noticeable brightness gain, it isn't what I would consider to be drastic. However, if anyone wishes to purchase a set of 2 then I will sell them for $5 including US postage - just PM me if interested.
In all of the side-by-side photos the button on the left is with my new 3D printed nut, and the one on the right is with the OEM metal nut. All phots were shot today at 4:00 with it being cloudy outside and the room blinds closed. I would say that the room is dim, but not dark. I used a digital SLR camera on a tripod set to manual mode so that all camera settings were identical for all photos.
