Jedi belt pouch molding suggestions

[janglesworthy]

Hey guys, I've made this Jedi belt pouch, 3d printed it out in resin and now I'm trying to figure out how to make a hollow mold of it. Right now it's a single piece, but I'm debating splitting the back panel off adding some keys and making the main body a shell it glues into unless it's easier to keep it 1 single piece.

Does anyone know of any books or sites that I can check out for reference, or have any personal suggestions? Any and all feed back would be appreciated. Here are some pics of one of the pouches, the other 2 have the same anatomy just different width and sizes.

Hi
In what material are you thinking for the casting?
I assume you want it hollow.
For a one part casting you could go for a two part silicone mold and try with a PU resin good for rotocasting such as Smoothcast 65d.

You might have to prepare a pouring holeand a plug for it in the mold in order to pour the resin and rotocast it (rotating the resin in the mold by hand to achieve a hollow casting).
If it can be a full piece then any PU resin could do.
PU resin gives problems adhering to itself once it´s fully cured so I wouldn´t go for that option. Other materials like polyester resin+fiberglass could do for that, but too messy for a small part like that. I would rotocast it or cast it full.

There are lots of videos out there as for silicone mold making.

Thanks for the help udog. I think the original prop is resin so that's what I'm going for. I don't know enough yet about different resins outside of 3D printing resins to make a solid choice. Here is a picture of the original prop, I personally can't tell if it's resin I'm just guessing.

Most probably resin. I´d take a look at the rotocast option.

soo.. anyone have any recommendations for companies who do low volume molding/reproduction in resin? I'm quickly realizing I'm not going to be able to do what I want on my own...
