So as I was wandering the internets, I came along this site: Patch Together They appear to make custom resin figures, and appear to be of pretty decent quality. The majority of their figures are miscellaneous kind of cartoony things, but they also seem capable of more detail (as seen here: Patch Together). Their business model seems to be you submit a design, get enough votes/interest, and then they'll put it up for preorder, and once they have enough preorders they begin production and shipping, and split the profit between the designer and the company. They also apparently do custom orders. So of course I immediately wondered if they could make custom parts or accessories, or maybe even whole custom transformers. Some of their figures seem capable of articulation, and some of the figures up for voting are more traditional action figures, with 6 swivel joints, weapon accessories, etc. So it seems they would at least be capable of making those types of things in theory. (See here for example: Patch Together) Not that I have anything in particular I would like to see made, but I know there have been some custom resin kits sold in the past (HOS Optimus Prime I think) and I thought I should bring this up so that interested parties can do some further research.
