Need Help with Backpacks

 All,

I’m working on another 28mm project.  Once again I’m using Warlord US Marine figures, but I need more backpacks because each sprue only comes with one for every six figures.  I’m trying to get my hands on about forty more; I’ve searched the internet but haven’t found any, and I’m reaching out to Warlord to see if there is any opportunity (though I’m not hopeful.   Nothing against them, it’s just that the sprue is set up with one each and they’re not going to pull one off 40 different sprues just to help me out).

This one:

So, does any other company make them? Are there any that can be 3D printed? Does anyone have any spares lying around they’d be willing to part with?

To be clear, I’m looking for the full pack with bedroll/shelter half, like this:

Thanks in advance, any help is greatly appreciated!

I believe this shall be my salvation:

Thanks to everyone for the recommendations to cast my own. I spent a bunch of time watching YouTube videos on this stuff and it looks super easy.  I went with Alteco 2-part epo-putty on the recommendation of one of the YouTubers, will let you know how it goes.  If that doesn’t work I’m looking at using a 50% green stuff/50% milliput mixture, also recommended by some YouTubers.

And here’s a sneak peek for those wondering why I’d need more US Marine backpacks:

Thanks again, everyone!

V/R,

Jack
