i use mold release spray, the shape is just like an original but I made some little channels for excess material to flow. i think i just need to widen them up a tiny bit so the bubbles can escape easier.

If you get this sorted you should for sure sell some.

I want a metallic purple cart shell when your mold is perfected. I am churning an idea inside my head since frosting donuts at work... make molds out of plaster and drizzle them with molten silver let cool and fill the rest of the way with plastic... could be cool if i get the setup hot enough.
you said cast in resin? is that what you made molds from, Chronoseptor?

I'm not a huge fan or plaster casting personally; it's messy and I don't like the way it smells, I like using Room-temp vulcanizing silicone for the mold, it's easy to cut, seals together well and is flexible so getting your cast out is a lot easier. I find it has a longer shelf life than a plaster mold as well and can stand up to more abuse. I don't, however, know how it will hold up to the extreme temps needed to liquify silver (I thnk in the 1700 degres F) and I don't know off the top of my head what the heat resistance of silicone is...

Timbob,
No worries, I assumed you just didn't find anything =P

Chronosepter,
Those look pretty rad, not quite what I'm shooting for but it's cool that you can make custom carts, did you make a resin mold or something for those?

Appreciate the responses guys.

How did you go about doing that?

I made a mold out of the two halves of an original cart with then cast it in resin.I haven't mastered the process yet so theres some bubbles in these.

I have a pink cart but its not Tamagotchi its a homemade job.

How did you go about doing that?

If anyone has one they would be willing to sell I would be happy to pay a reasonable price, considering they are fairly rare. Condition is important to me here as well, I would like one that isn't badly damaged or scratched and that isn't stained or discolored in anyway that couldn't be cleaned.

Thanks guys.
