Hybrid  Cage

The best of both styles

This chastity cage combines the Cell and Voronoi styles together. In homage to the Cherry Keeper TouchStop, the voronoi pattern  prevents you touch your dick, while the cell provides the strong dominate lines. 

The voronoi pattern is off set from the cell giving a striking appearance while being completely flush with the cell on the inside.

KB3D Cage V4

2022 is a big year for the KB3D cages, as I am pleased to introduce version 4. This takes forward the strengths of V3, while taking the recommendations from the chastity community to take this to the next level.

Redesigned head

Although very comfortable, a negative of the V3 head was it was very large. 

Version 4 redesigns the head reducing the empty space. This provides a more supportive and better looking cage.

Curved from the beginning

V3 did not originally start with a curve, which was fine for the nub wearers out there however, once the cages start getting larger than the milli. The cage required to be curved or it would be too noticeable.  Therefore the curve was added as an afterthought.

V4 the curve was designed from the beginning. Hopefully conforming to a more natural shape.

Spikes for all!

One cage you may have noticed was missing from the Chastity lab was the Stinger.

This popular cage placed ~30 spikes across the head and shaft of the cage. 

Well, we thought... "Why not at the option for all style of cages?"

And that is what we have done. On each style where you see the spike symbol, this cage is available for the Stinger Treatment!


Give Me More!!!! Styles

With a new generation comes new styles, such as this hybrid. Please get in touch if you have a style idea. 


It's still a KB3D Cage

The customizability of the V3 made it a great choice for whoever wants to add their custom flare. 


V4 has the same great colour range as the V3, and is still backwards compatible with V3 rings. (Although I would recommend the V4 ring).

Chastity on a budget

Applying the finish takes time.  As I'm doing this in addition to a full time job, this disproportionately increases the costs. 

If you're happy to apply the finish yourself, you can get a high quality device, cheap!

Only £35 (save £20)

Applying the finish makes up a big chunk of the device costs.  


We have a full guide in our "Guides" section on how to finish the product yourself, so you can save £30 by purchasing an unfinished product!

KB3D Cage Guide


The Finish

This refers to the sanding and sealing of the cage.  After printing, the cages aren't perfectly smooth, so need to be sanded and sealed for comfort and hygiene purposes.  To learn why this is important - Click here.

KB3D devices are finished by hand to ensure they're all finished to a high level. 

If you would like to save yourself some cash, you can buy the product part/unfinished and finish it yourself.

The cages are designed to fit a standard internal chastity lock.

So, if you already have a lock and key, that you can use with our cage, then save yourself some money and reuse it! It's better for the planet that way too.

If you do require a new lock, it will come with two keys.  These keys are not replaceable, or interchangable.  Look after your key like your cock depends on it! It does!

Lock & Key

Interchangable slower

Mix it up! Or replace parts

Each of the cage designs should fit each of the base rings, regardless of the size of the cage, or the size of the ring. 

This way, you can mix and match! Got the perfect ring, but want to change the cage?  Save some money, and save the planet; reuse what you already have.

When requesting a quote, if you do want the full device, you'll need to tick the box for each part (cage, ring and key & lock).



I design and manufacture each of the cages myself.  If you have 'unique' dimensions, or special requirements, I am open to adjusting my designs to fit your body.

If you need a custom size as you're bigger/smaller/thicker/thinner, or you need a custom shape as maybe you have piercings, growths or you're missing body parts...  I'd be happy to work with you to produce something that works. Fill out the form to request a quote, but give me as much detail in the comments as you can to understand your situation.  I'll contact you when I have availability to work on designing you something bespoke.

The added time required to design and experiment would be reflected in the quoted price.
