The way I am structuring the Kickstarter is thusly:
Goal $ - Gets one wall panel and one floor panel 3D-printed in high-detail.
Initial design-work has already been done on a blank/featureless 6"x6" interlocking floor-tile. *RIGHT NOW* the designer is working on creating a textured version of the floor-tile using a purchased design. There is a tab-n-slot system that - according to our modeling program - allows the floor tiles to lock together from any side.
Initial "proof-of-concept" work was done on the first wall panel earlier today to identify unprintable areas. I think a couple of the guys will be happy to hear the first panel will have exposed piping.
The walls will have a tab-and-slot system similar to the floor tiles so that they interlock, as well.
We are planning a ceiling series, as well, whose interlocks will work with the walls in the same way the walls and floors fit together, allowing dio-builders to put together a complete one-sided corridor of a strip of floor tiles, wall tiles, and ceiling tiles that all lock together, or an alcove display of a floor, 2 walls at a right angle, and a ceiling. Today has me convinced this is VERY possible.
Stretch-goal 1$ - Adds another wall panel into production.
Stretch-goal 2$ - Adds another wall panel into production.
Stretch-goal 3$ - Adds another wall panel into production.
...and so on.
Our initial plan was a series of one floor-tile and 6 wall-tiles. We may modify this plan slightly, by adding floor tiles in as stretch goals, either alternating with the wall tiles or have them occur as pairs - every stretch goal unlocks a floor AND a wall tile. Plus, we discovered our wall panels are actually double-sided, adding to the number of potential walls we could offer. I'm leery of overextending our first series on the Kickstarter campaign, though. If the demand is there, we can always come back later and run a series of *new* floor and wall tiles.
PLEASE go ahead and ask questions, Tamer (and everyone else)!! That way, if *we've* missed something, your questions will catch it and we'll get it addressed BEFORE we are 5 miles up the river in Injun Country!
