This is a 3D-printed base I made as a Christmas gift for a friend, which uses a NeoPixel ring and a Trinket from Adafruit to illuminate a glass Klein bottle from http://www.kleinbottle.com/. All of the electronics are integrated into a two-part 3D-printed base that can be fastened together using M3x14 screws. A spherical scallop cradles the Klein bottle, but matches the curvature of the bottle so perfectly that there is very little friction. To prevent the bottle from fall over, small dabs of hot glue are added on top of each M3 screw, holding the glass upright surprisingly well. A video of the completed piece in action can be seen at: https://www.youtube.com/watch?v=YRprDHtTOR4 Photos from the assembly process can be found at: http://www.flickr.com/photos/zenwebb/sets/72157638778949224/ More photos of the completed piece can be found at: http://www.flickr.com/photos/zenwebb/sets/72157638776800776/ You can also find an article about this piece (and another gift) on my blog at: http://jason-webb.info/2013/12/glassblowing-electronics-first-commission-and-klein-bottle-gift/Apologies in advance for the lack of very clear documentation - this was created as a one-off gift for someone, not necessarily as an easy project for anyone to make. I hope I've provided enough for you to do it anyway! Photos from the assembly process can be found at: http://www.flickr.com/photos/zenwebb/sets/72157638778949224/
