I've just about finished Mark4 of this build. Sadly, the way it was designed it won't be 3d printable, but I'll leave Mark3 up so people can still print their own if they'd like.
The entire thing was redesigned from scratch, including new transformations and tighter details. LEDs will be included in the head, chest, and canon for a nice glowing effect.
There are a few errors in the rendered picture, but I've got a few days to work those out. Just wanted to get this out there in case anyone saw any major errors or thought I could improve it in places. I'm open to any ideas!
Once I have things finished and in hand I'll update this instructable and lay things out in a more organized fashion. This is a bit of a mess right now.
Updates are regularly posted on TFW2005 and Twitter.
Step 1: Design:
Once I had the basic idea of what I wanted, I found some blueprints of the 11th Doctors Tardis and got to work recreating it. I wanted it to be a show accurate as possible. Then I printed out a 20mm vertion of it and cut it and worked with the clay again to make sure all my ideas would actually work.
Then came blocking out the basic shapes to get a feel for how things would look and be positioned. As you can see in the pictures the design originally started a bit differently. I had to make sacrifices to certain aspects of things in order to make sure I had clearance to make him transform.
