About
It really wasn't anything I'd ever planned to do. I just designed stuff I wanted to use on myself which didn't exist in the marketplace.
It was obvious to me for example that whoever was making the various balls electrodes on the market had almost no experience or understanding of the way current travels.
The ridiculous OxBalls testicle bag thing is the obvious example of this. Both contacts are side by side at the bottom of a huge rubber sack that only fits frankly bovine males. Because of the stupid contact positioning, current travels through the scrotal skin and never goes near the balls and that feels totally horrid, just a burning stinging sensation.
So my testicle box design tried to address this, with my fairly basic understanding of electron flow I reasoned the contacts should be either side of the balls. I'd just bought a basic 3D printer and this enabled me to design what I thought would work far better.
Here's the first prototype:
This actually worked really well in use, the feeling was completely different to anything I'd tried before, a delightful mix of pain and deep pleasure. When I put pics on here and Twitter the reception was very positive and many people wanted to buy one. But I couldn't really help them, what I'd made had taken days to finish to a reasonable standard as what came off the printer was pretty crude. The printed bits had to be filled in places, sanded and then sprayed to make them look reasonable and the brass parts had to be milled on my lathe, there was no way I could productionise such a long process. Also it was sized for just me, it was never intended to fit anyone else.
Version 2 tried to address the sizing issue, so that I could use it on male subs, by mounting the contact plates on screw in knobs which allowed the distance between them to be adjusted. Usage experience also showed that this feature allowed for a certain amount of squeezing of the captured nuts, so it was win win!
I still couldn't really sell the things as each still took far too long to make, but I did start making replicas for close friends and for some heavy duty CNC prisoner events to torment the male "guests".
A year or so past in which time I upgraded from basic FDM printing to resin printing, which is smelly and messy but produces far better results. This meant I could now produce my testicle box in about a day to a much higher standard, here's Version 3:
