I love this mod so much so I had rebuilt part of it for myself. One of the pieces I added with Space Age was to have a foundry compatible version. I unfortunately lost it...is that something that you will add in? Is that something I can add for you?

Glad to hear you like the mod! :D
I am going to add proper Space Age integration at some point, but it might take a while.
For foundries, I'm planing on adding recipes for Raw Plastic -> Molten Plastic -> Plastic Bar, is there anything else you'd like to see?

That's the main thing. I'm not sure if anything else really fits...
