Instructables
Noticing that my breasts provide a source of comfort for my partner, I decided to take matters into my own hands and make him a personalized version of a classic erotic novelty: a squishy boob-shaped stress relief toy, modeled after one of my very own. Maybe now he'll leave me alone so I can get important things done.

This is the second part of a two-part series on making a silicone model from a human body part. The first part of the series was Replicating body parts in plaster.

Step 1: Go get the stuff you need

Picture of Go get the stuff you need
You will need:

- 1 pint of Dragon Skin Platinum Silicone Rubber
- 2 pints of PMC-744 Urethane Rubber (although, considering this triggered an extreme allergic reaction in both my assistant and I, I'd recommend using Rebound 25 silicon rubber, if possible)
- Smooth-On Universal Mold Release
- Ease Release 800
- Shellac or lacquer sealant
- 2 two-pint measuring bowls
- 2 cheap paint brushes
- 2 wooden mixing sticks
- a plaster cast of a breast
- a white painter's body suit
- a pair of thick rubber gloves
- a pair of nitrile gloves (non-latex)
- a couple of thick garbage bags to dispose of chemicals
- an empty 2 gallon water container
- a razor blade
- a hot glue gun
- duct tape

***a well-ventilated area or a nice, windy spot outdoors***

Step 2: Seal the plaster

I did mine a little backwards (built a frame around it and then coated it), but before you figure out a way to house your plaster model, you should seal it with shellac or lacquer. Apply a few quick, thin coats until it is completely covered. It's best to use something that is colored so that you can see whether or not you coated the whole thing.

Once the sealant is dry, spray the inside of the rig with Universal Mold Release agent. Gently spread the release agent around with a paintbrush and then let dry for thirty minutes.

hello! great instructable(s) I know of a few ladies that have undergone mastectomy and this technique can be very helpful in making prosthetic breasts for them, nice work!
Good point. This would especially be a good project for someone BEFORE the mastectomy. That way they would have an affordable prosthetic shaped exactly the way the were before. (That is, if they liked the way/size they were before)
***Bad Joke Alert*** If you inserted one of those led tealights into the silicone before it cures, you'd have yourself a nice led teatlight. The fellow posting about constructing a certain computer input device, using this method, neglected to refer to it as a titmouse.
Trololololol.
it would have to be something like a Mac mouse, what with only one button...
Unless one was to engage the modelling services of Betsy Triplenipple, former resident of Three Mile Island, Pennsylvania.

Hey Donna, Thanks for being so open and sharing this wonderful tutorial.

My guess even with the "stress relievers" your partner isn't leaving you alone at all. In the event I'm correct what's plan "B".

@donnauwanna great instructable, your info helped a lot on a project i was working on at work. We are making a demo for our product and needed a dummy to represent human anatomy. FYI I tried both dragon skin and Ecoflex 00-10 for the molded part and found that Ecoflex was a much better representation of how fatty tissue feels. When Dragon skin is poured thick it seems like it is pretty dense. the EcoFlex was much squishier. For those looking to buy the silicone, I found them both from the company website at www.Smooth-on.com

Where can I buy / what do I search on google to get the dragon-skin silicone? I've been searching, but I can't find any. Also, is there a way to tweak the turgor (squishyness) of the rubber? like adding more B than A? Thanks

getting a willing person to mold their breasts is definitely a challenge.

Can you add tint to make them flesh like looking?
It just occured to me, how about plaster cast gauze your boobs and set the cast. Sand the inside of the cast down to get it smooth.... and then fill the cast with silicone.

another use for this would be to immortalize one's breasts in the event something catastrophic like breast cancer happened, then you'd have a guide for the plastic surgeon for reconstruction purposes.
You're a genius!
hehe, what can I say? Boobs are serious business. *wink*
may i add bow chicka bow wow
Yes you may. lol
Boom chicka wow wow... chicka chicka!!

there's only one itty bitty problem, you kind of need access to breasts in order to mold them. that's a problem for me.
