Didn't have much time this week, so this is the best I could figure out for mechanical area. I'm sure it's possible to build the molecule without full access to the bonder and debonder, but I didn't have the time to make it work.

Solution name is because this looks a lot like a min cost solve except for the calcifier, which could have easily been removed but would increase cycles. Also the duplicator probably isn't strictly necessary if you make a waste chain, so maybe there are 2 asterisks
