New KTB, 3D printed

What is the internal diameter?

 

Where can you get the e7 insert? I looked on the website, but there seem to be 4 different e7's.

 

I the martial is flexible. One could fix a strap from one side of the tube around the scrotum back to the other side. You could test the material, width, lenght, and thickness for fit by fixing it with white school glue that disolves in water. Once you have a good fit you could use super glue or perhaps five second fix to weld/solder the strap permanently. You may be able to use the blunt nubs at the end of the tube for a better anchor.

Does this sound like a reasonable field upgrade?

...
If you were looking for something more adjustable and not secure, you could simply use a shoelace.

No matter what you do to make any device secure there will always be some way to escape. It is far better for the manufacturer invest in the heath and safety the device to the wearer. And for the chaste to invest in the relationship to/with the keyholder. Everyone wins.

 

I used to wear a homemade KTB over a decade ago. The points of mine were sharp metal staples. There were many so the bed-of-nails effect prevented puncture.
Concider adding a warning on the sales page advicing not to wear the KTB while sleeping. The wearer's sleep will be unavoidably damaged when nocturnal errections occur. One of the main, if not the main, missions of the device is to channel conscious thought there is little profit in using it when unconscious.

 

It looks like a CB6000 base ring may be able to be used with very little modification to the KTB or the CB base ring, but KeySafe would have to give the diameter of the locking pin to know better.

 

Unless you have a penis the diameter of a magic marker you should think carefully about this. The diameter between the spikes on the one we got is 19mm (less than 2cm). For the other Imperialists out there that's just a hair under 3/4".

You'll see in the pics below that it fits snugly around my middle finger. Look at your middle finger, and imagine cramming your manhood into into the space it occupies.

The recessed spikes are as forcefully pushed against you as the non-recessed, as the amount of their recess is tiny. Which combined with the fact that you're so crammed in means that you absolutely ooze between the spikes.

Like I said, if you're exceedingly narrow this may work for you. But I practically broke it to get into the thing since you need to bend it to squeeze in the top. Once on we just kinda shook our heads.

We'll try it a few times, I'll cry, she'll laugh, then we'll try sanding the spikes down which won't work and that will be that.

Great idea, but unlike many other products on Shapeways you don't receive an email requesting your specific measurements. So apparently this here is what you will get. If that's your jam, go for it. But if not. Consider yourself warned!!

 

I'm wearing it now. A punishment for smoking. Surprisingly comfortable actually. Well not comfortable, but you know. Though I'm terrified of getting any kind of hard-on.

 

Yep. @Thatguyontheinternet knows how I HATE smoking. We had to cram his little guy in there, but there is absolutely no room for growth...not even a semi! He will be wearing it for awhile tonight.

 

So, much to @Thatguyontheinternet chagrin, I messed around with him for a few minutes while he was wearing the device...He tried to fight me off, but in doing so started to get aroused! As his member swelled, his eyes got bigger, lol! Needless to say, it is a cruel little mistress of punishment. I went ahead and took it off after a bit so he could sleep without it and told him that he had better be good or else he will be wearing it much more often (His PA is in the toughening up stage now)....and i'll make him watch his favorite porn with his hands tied behind his back as punishment. Needless to say, he quickly agreed and said he would be a good boy

 

It definitely works. @Thatgirl sent me a message before I left for my open house today that read "Before you leave, put your KTB on, lock it and send me a pic. Put the necklace with they key on my beside table". So she is definitely liking having an option that can be used while I'm still healing up enough to use a cage. The leather belt is rough because its kind of bulky and cumbersome. This fits nicely under clothes, but MY GOD. It bites!

 

So...here are the results of wearing the device for 9 hours today. This picture was snapped as soon as the KTB came off:

 

Really neat. Shows it does its job wonderfully. That'll keep him in line for sure, plus the knowledge that you COULD have him in one with some REAL spikes.......

 

The mild one should arrive this afternoon, I'm not sure if I should be happy or scared Both, probably...

 

Thatgirl, you were a submissive girl who turned into a domme? I'm saying that because I red an other post from you about that and when I'm reading now this post, I need to understand.
My GF is in fact submissive, but she's vanilla, however she HATES that I can masturbate, so she agreed to make me wear a CB. Why do you think of that?

 

I think, "To each their own." I was never vanilla, just submissive, and just to @Thatguyontheinternet. Like many women, I hated the fact that he masturbated because I have a sex drive that rivals most mens. Sometimes I wouldn't know that he had "taken care of business" without me earlier that day, and I would make advances only to be told that he had jerked off. He agreed to the cage one day when we saw one in the porn shop - it had piqued our interest, and everything kind of evolved from there. It has taken me a full year and I am just now getting the hang of being more Dominant. My submission left long ago for me. Here is my advice: Your girl is vanilla, yet submissive and you want to remain locked for her and not touch yourself since she does not like the fact that you do. Just stay locked, give her the key, and whenever you feel like sex or she feels like sex, have her unlock you. She agreed to the CB because she does not like you masturbating and the fact is that many women feel like it disrespects them and gives a blow to their self-esteem since the masturbation is usually accompanied by unrealistic pornography featuring unattainable and fake women.
