It would help to include a link to your Kickstarter and some images to show what you are trying to Kickstart.
I would also suggest having pictures of finished or printed pieces. The 3d renders look good for some of them, but without seeing them next to certain figures to get an idea of 'original scale' (I know they can be scaled, a great thing about digital files) it makes it harder to commit (at least for me).
I like the spider mech, but without seeing how it is cut I don't know how it would print on a SLA/DLP printer which I tend to use more than my Prusa or
CR-10.
