This is one for the vagina owners out there.

I have designed a 3D printable vaginal and anal Bipolar Conductive Rubber Electrode that I am calling my Bitter Pill.

Each Bitter Pill Electrode will be printed in my trademark YELLOW PLA. This insulator has two lengths of 8"/20cm of 6mm conductive rubber tubing that takes 2mm plugs.

It features two loops, one for each orifice and the top of the electrode carries a raised "V" for the vagina and "A" for the anus, so you don't mix up the loops when you use them again. The sides of the electrodes feature two loops for attaching knicker elastic so you can secure it in place.

This extremely clever design has each side of a loop touching at the top to ensure smooth current flow but each electrode is isolated from the other, making this a bipolar electrode with one pole in each orifice.

It will be dispatched un-painted but with 6mm conductive rubber tubing already fitted. Your TENS cable plugs can secure to either end. You can even use either electrode loop as a base for tri-phase play by plugging a cable into each end. The sockets are labelled "V" and "A" at either end, so you know which loop you are connecting to.

Just plug in your 2mm plug and then insert it into your vagina and anus before switching on your control box and experiencing some e-stim pleasure.

I recommend that you paint it first, though, to seal the surfaces with a plastic paint such as Krylon Fusion For Plastic.
