Anyways, I think I may be interested in tips on how to build connector pieces for everything. I've read several articles about scratch-building, but I don't know what materials I would need, where I can get them, and whatnot.
I would like to say though, that Scavenger and Quickmix transform perfectly into legs, Demolishor requires little transformation, and I did nothing to the top three.

So until I get duplicates, or the materials to build the connectors and Devastator parts, here is my Work NOT in Progress diagram with missing parts drawn in

P.S. That's my sister's puzzle table, mines a mess, so I apologize for the background.
