3D Printed Male Chastity Device Prototype: Personal toy for men

For those couples seeking to spice up their personal lives with a bit of power play, leaving the woman in charge of the action (as it were), some inventive makers are hard at work prototyping new devices. We’ve looked recently at Dame Products’ 3D printed prototype for the female-use Eva product; now it seems to be the men’s turn for their own toy.

Discreet packaging from Shapeways ensures privacy in transit

One of the latest prototypes out there, comes from Shapeways user pedro69, and has been tested out by a friend of his who runs the Become Her Slave blog, which focuses on men who want their female partners to dominate them. This new prototype — the Keyholder Dream (KHD) X3 Espresso Short — is a “male chastity device” that keeps a man’s bits securely in place and puts him at the (playful) mercy of his partner, who quite literally holds the key.

The blogger, Giles, received the prototype in the mail courtesy of his friend Pedro, and was pleased that it arrived in Shapeways’ discreet, professional packaging, already assembled. The only work to do for the piece is inserting a separately-purchased trailer hitch lock, which slides right into the crafted opening.

Of course, following completed assembly, the entire unit was washed and sanitized for use — keep in mind this is intended for intimate use in a sensitive area; hygiene first! The 3D printed material makes the device dishwasher safe.

After preparing the unit, Giles tried it on. To put the device on, he found a four-step process worked best:

1. Without lotion, install the base ring as snugly against the body as possible. Make sure it’s aligned right, it’s almost impossible to twist the thing once it’s on.
2. Apply lotion to the penis and the upper inside surface of the tube. (He notes later that “Thanks to the espresso perforations, the lotion quickly disperses, leaving your penis dry.”)
3. Install the tube. The penis should slide right to the end.
4. Lock the device. 🙂

I take his use of that final emoticon as a sure sign of customer satisfaction. In comparison to another device he already owns, Giles notes that this piece is “generally comfortable to wear” and “really comfortable to sleep in”. He also notes that for its intended purposes, it provides a “wonderful sensation” when aroused.

The 3D printed material was especially favorable in Giles’ review, for both its comfort and its feasibility for production. He points out several key features pertaining to the make of this piece as he summarizes his thoughts:

“Pedro’s chastity device isn’t perfect — it’s a prototype. However, it’s nearly perfect and already much better than the cheap Chinese device I have. A few tweaks and we’ll have a cheap robust male chastity device with a magic locker and a pull-out detector, available in a huge range of styles and sizes, 3D-printed on demand.”

Some of his further thoughts reflect on the pricing of such devices and the future of their manufacture:

“Hobbyists will push down the price of chastity devices. Pedro’s betas come in at between EUR80 and EUR100 plus postage, but I doubt he could push the price any higher even if he wanted because some other hobbyist would undercut him. And 3D printing is only going to get cheaper.

The quality of male chastity devices will improve. 3D printing lets amateurs and moonlighting engineers like Pedro tinker with designs and then update their product almost immediately. Contrast that with how long it’s taking Holy Trainer to fix their design and material issues thanks to having to change their manufacturing process, deal with contractors etc etc. The market will soon no longer support chastity devices that pinch, crack or snap.

People will soon prefer to buy 3D printed chastity devices. Not only will they be cheap and made to measure, they’ll also have the major advantage of being manufactured locally, getting around the whole import duty hazard.”

Users of these and similar devices have high quality standards and expectations, as well they should. The points brought up in this review are all sound, and very much reflect what we’ve been seeing going on in the general 3D printing industry. Starting with low-cost prototyping, final devices will continue to benefit from multiple iterations as the design is finalized and improved upon. The applications for 3D printing extend now into every aspect of people’s lives.
