I have designed a 3D printable Monopole Conductive Rubber Coronal Cock Ring Electrode. The design is finished and is available for download on my Gdrive, so if you have access to a 3D printer so that you can make one yourself.
However, if you do not own a 3D printer then I am offering a service where I will print one out for you and send it to you. This Electrode will be printed in my trademark YELLOW PLA. This insulator comes with 12"/30.5cm of 4mm conductive rubber tubing that takes 2mm plugs. This version comes with three stainless steel amplifier balls to put pressure on your glans and to form a good electrical contact.
This novel design only uses one length of 4mm conductive rubber that is locked in place at one end with a pin, and then fed through the two 3D printed components to create the coronal cock ring.
It will be dispatched un-painted but with 4mm conductive rubber tubing already fitted most of the way through it. You will need to feed the conductive rubber through the final hole to get it ready for use (it fits in the packaging easier without it being fully assembled).
One side of the Conductive Rubber loop has a pin fitted to secure it in place. Your TENS cable plug secures the other end, you can remove this plug to allow two plugs to attach to this electrode from different channels if you are using a Tri-phase set-up to make it the base connector.
To fit it you loosen the loops and place it over the head of the penis, then tighten the horizontal loop before drawing the loose conductive rubber down through the vertical hole then attach your 2mm plug to the conductive rubber.
I recommend that you paint it first though to seal the surfaces with a plastic paint such as Krylon Fusion For Plastic.
Note: This product is supplied as is and I am not liable for any problems that arise from its use. It is sold as a novelty item and carries no warranty. Your statutory rights remain. Images shown are renderings, the printed product will show some layer lines and require a light sanding.
I will be sure to Cum back again to purchase any other products that I need.
Thanks again for your help and I will recommend your site to others.
