I originally had all the buttons and LEDs as part of the case, but found it difficult to paint (I'm no masking expert!), thus I created all the buttons separate to make it easy to print (and possibly print in separate colors ??!). Once all the parts...

Pro tips: You can use a rope, led inside the legs of the device or the hook part, to obtain an even tighter fit, or to construct a g-string like a wrap around you. If you mount a small bullet-vibrator (or even a big one :D) with a rubber band or a...
