Hi naughty one! So you'd like to have fun with kinky 3D printed models?! You are right ;)

But on Cults, little bunnies have to prove they are grown up enough.

3D model description

See also the "Lite" version here:

Designed to preserve the health of the wearer and support him in attempts to become more detached from sensual pleasures.

This is a device to be worn voluntarily which can prevent some impulsive releases and help break the cycle of masturbation.

Unlike many chastity devices, the device permits full erections but does not allow the wearer to stimulate himself while in this state.

Ideal for day and night wear in the home. Can't really be worn in public with pants with a typical, modern low waist; to do that, suspenders or clothing of a different style would be required, or the upperclothes should be draped over the top to prevent embarrassment.

Designed for a man of average endowment (6" length erect.) CAD file (Fusion 360 format) is provided in case modification is desired (see below for mod. instructions)

CAUTION: Though it has been designed with health in mind, this device has not yet been tested for long-term wear. Use at your own risk. If using version number less than 89, be especially careful of pinching the scrotal skin on the left.


  • Prep 1: Acquire at least one small luggage lock or other means of securing the lock pin (ideally two, one for each side.) If a keyless experience is desired, a length of twine can do the trick at the expense of having to tie/untie it when putting the device on and taking it off. Amazon Link

  • P2 (Recommended) Get some elastic to put through the belt loops. Amazon Link

  • P3 (Optional) Sew some cloth around the lower bar of the base ring to reduce clinging/tugging. Amazon links: fabric thread

  1. (Optional) Put a rubber band around the testicles

  2. Insert the genitals into the base ring. For versions including the testicular enclosure (<90 or so,) work the testicles into the enclosure one at a time.

  3. Carefully mount the main enclosure onto the base ring while keeping pinching of loose skin to a minimum (This can take some trial and error.) Overlapping the right side first, then doing the left side while averting pinching, then finishing the right side is recommended.

  4. Secure with the lock pin and luggage lock(s). Inserting the pin in the opposite direction as shown in the picture has been found to be more convenient.


Modifying the user parameter "Member_length" in the .f3d file can help change the fit of the device if a larger or smaller chamber is desired. Other modifications may be necessary, but the file is somewhat well-labeled.

Modification/individualization may be provided upon request.


In the interest of promoting the public's pursuit of spirituality and detachment, the design was provided free of charge while in early development.

Nov. 24 '21: Split holes on mid piece to increase structural integrity. Removed unnecessary middle curve from scrotal port on midpiece.

Sep 28 '21: Modified shape of lower portion of base ring to increase comfort by accommodating the frontal corpus cavernosum. Removed longest vent on front and increased structural integrity of circular grill.

Sep 12 '21: Added waistband loops. Removed front waistband piece and chain loops. Removed lower enclosure. New STLs are split more to reduce overall print time and reduce wasteful support material.

Aug 30 '21: Modified shape of scrotal port to reduce uncomfortable compression of frontal corpus cavernosum during erections without base ring

Aug 29 '21: After real-world testing, added rails and a secondary lock hole to the left side of the tubing region to make the device easier to put on and to give the wearer a safer and more pleasant experience. Added hole for waistband on front of device. Small ease-of-print improvements to midpiece. Reduced length of main chamber slightly. Lowered "ceiling" of right side of lower enclosure to prevent pinching. Expanded front of main enclosure slightly.

Aug 27 '21 (Evening): Raised "floor" of Low piece to increase wearability and comfort

Aug 27 '21 (Morning): Added small cuts where midpiece contacts base ring to alleviate pinching, reduced diameter of small lock pin head

Aug 26 '21 (v69): Further modifications to the lower enclosure have been made (not pictured.) The right half has been lifted somewhat (to fit the typical anatomy better,) and the overall width has been reduced (the previous version was unnecessarily wide.)

Next iteration may feature a reduced upper cage that will fit more easily into modern Western attire at the expense of pushing the erection to the left.

8/24/21, 7:00 ET (v53): Third revision published. Lock pin and corresponding holes scaled up slightly.

Aug. 24 '21, 2:13 PM ET: It's come to my attention that the initial model may not be suitable for men with a tight scrotum, and that the pin required modification to accept a typical luggage lock. A modified model attempting to address these issues has been uploaded.

3D printing settings

Approximate overall size is 9" vertical span, 7" horizontal span, 4" depth.

To print on an Ender 3 or printer of similar volume, print in 4 pieces:

  1. Low piece (Base Ring + Low Enc + Inner Tube)
    Recommend rotating this piece by 90 degrees in your slicer such that the "front" faces upwards

  2. Mid piece (Main Enclosure (B) + Outer Tube)
    This piece takes the longest and can be finnicky. Recommend blocking supports on the slits on the right, and printing with the cut section on the build plate (as if the build plate cut it.)

Reducing print speed might help prevent flaws in this part, but with recent changes may not be necessary.

  1. High piece (Main Enclosure, Top Half)
    Recommend printing in similar fashion to mid piece.

  2. Pin (for lock)

After printing, support removal, deburring, and sanding, superglue or otherwise affix the slices of the main enclosure.

Please feel free to comment with suggestions and feedback.
