Klein bottle (medium) NeoPixel base

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.
