Refrigerator / Preservation bin / Fridge

Ok title hopefully has the keywords I need.

I’ve done 3 mods that I’ve figured out by trial and error, and now I want to add organic polimer preservation to one of the mods and figured I’d ask if anyone has done something similar and where to point me to avoid mistakes?

Off topic one of the best mods I’ve seen (and been trying to figure out how he did it) is the Recyler mod that converts any object (including other mod ones) back to resources… saves a ton of time in gathering when you can destroy useless junk! So if anyone has done something similar also point me in the right direction please!
