(exp) Good evening, i found out about your proyect and i'd like to hear more about it, i myself just started collecting Gunpla and i have in my posetion an RX-78-1 Entry Grade that i can use to measure some components.
*What i know about Gundam*: i am familiar with some of the series, personally i only watched the original one, Z Gundam, ZZ Gundam, Unicorn and Wing, so i can't really tell them all apart, maybe i can identify some from G Gundam but in general i understand the gist of it all.
*About your proyect*: to my understanding you want to design printable conversion kits, as in "a set of pieces to turn one Gundam Model that's currently aviable for purchase into another one that isn't for one reason or another", that sounds interesting, depending on what you got to work with (a 3D file to strack the components from, for example) or any measurements, this proyect can go smoothly, i can work from only images and references but there'll be a lot of "artistic interpretation" wich, can be resolved easily through a little bit more of back and forth, the amount of time it will take, however, depens where we start from.
This is a proyect that i find quite interesting, i for once, for example, always liked the idea of owning a "Tequila Gundam, being Mexican and all, however moderns sensibilities makes it so, i get why Bandai wouldn't want to put one of those for sell, anyways, i'd be waiting your response.
