How did I not think about this earlier??

I usually like to play with bottles as they come in all shapes an sizes and are readily available. But it's quite awkward to walk around and sometimes the lid can be a bit uncomfortable.

I found the perfect sized and shaped bottle but couldn't find a suitable plug with similar dimensions. Then it struck me (knowing this is not a new idea, but for me it was): I can just mold the bottle with plain old silicone from the hardware store. Once it's fully cured it's completely safe to use, easy to clean and it's not even expensive.

I cut off the bottom of the bottle and filled it half way, then I added a wooden round bar in the center for rigidity. Afterwards I can trim it to length and cut off the lid part.

I'm pretty excited how it'll turn out and if it works as I expect. Does anyone else have experience with that idea?

It won't work well.

 

It'll stink badly while new, it'll be more pourus than you expect, it'll hold bacteria, and the chemical within that could really irritate you.

 

If it works, let us know.  But I tried once and it didnt.

And depending on the vigor with which you use it it may not be strong enough to withstand the pressure form the stick which would result in a trip to the ER.

yeah I kinda saw the same happening with a lot of bubbles forming, and it wouldn't have had a smooth surface. Biggest problem I have right now is that it doesn't cure as the solvents can't evaporate.

nah I don't think so. I turned the wooden core on my lathe to fit properly and sanded it very smooth. If the silocone wouldn't hold, it would just shear off and I'd have a nice wooden dildo in my ass.

 

Nonetheless, I think this was a fail. I will invest in proper food safe 2k molding silicone and do it the right way.

look up permaflex silicon. they make several different grades of silicon that u can use with varying levels of rigidity.

thanks for that, but I don't think that they ship overseas in small batches.

I got some stuff from ebay but Shore 35 is definitely too hard. The plug I molded wasn't very comfortable and I nearly popped a blood vessel in my brain trying to get it back out.

So I ordered some way softer silicone (shore 22) and will give that a try. Let's see how it works. I might even get fancy and do this variable hardness like the high end toys, with a harder core from the shore 35 left over and a soft outer layer.

You just need medial grade rta/rtv Silicon. And try shore a00 through a13 anything above is too Hard.

I finally got to mold and try out the shore 22. It was way better than 35 and super comfortable to wear even for longer periods.

The plug has roughly the firmness of a fresh bottle of soda, so a fair bit more than one  just filled with water. It works great for my taste, but just for the giggles I will try something softer like MaP91 suggested.

Only problem I now have is getting the plug back out, as there is not a lot to hold on to like it was with the whole bottle. I will probably mold in a wooden core again and include a threaded insert so I can attach a handle or a rope to pull.

Now that I got a hang of the silicone molding, my next project will be customized shapes. I found that most soda bottles will shrink if you heat them up. So I can create a wooden template on the lathe or carve by hand, put it in a soda bottle, shrink it so it takes the shape of the template and then mold it with silicone. Next step would be to create a mold off the template and skip the bottle step.

Buying toys would probably be way easier and cheaper but I just love the process of crafting myself.

Try a 3d printer for molds. I just design toys in cad programs and print a mold with an 3d printer.

that's a pretty neat idea actually. Unfortunately I don't have access to a 3d printer... at least not in a way that I could print that sort of stuff.

What material/silicone do you use to pour?

go to an arts and crafts store and get kneadable clay. it wont harden (set). i do not remember the exact name but  you can find it in the sculpting section.

the more you work this clay ,or get it warm, the softer it gets. use this to sculpt out your toy. you can reuse this stuff over and over. i also used lego's to make the frame for my molds then using hot glue to seal them to a cookie baking sheet. i got a little creative at work when i was creating molds for some of stuff we used to produce.
