Here are all the photos included in the email, in the order of appearance:
'"Tough" SLA disc ejector mechanism v4' and the 'MJF Nylon, improved disc ejector v7'. Interestingly neither of these show the 'rocker flap' which keeps the movable disc cradles from extending fully (as two are shown doing in v4 and all do in the v7 version) though one can see in both where it is attached (red). One can see this 'flap' in a photo from an earlier Update:
Another interesting thing those two photos tell us is that the speaker is indeed facing DOWN (see the silver disc to the right on pics), with a seemingly 3D printed resonance chamber below it, presumably open to the lower compartment in order to direct the sound into the larger empty(?) Lower Compartment for richer, less muffled sound.
Here we see the printed Tricorder along with the final product of the Phaser and Communicator:
I really like this photo. It definitely gives a great sense of scale. Interestingly, I've always imagined the Tricorder to be much larger. Heck, it's not even as tall as the open Communicator. And I don't think you could even fit a single Communicator on its side in the lower compartment, let alone two vertically (as suggested in Wah's original drawing):
Moreover, the photo of the trio tells us TWC will be using a similar style display base as well - probably magnetic like the other two bases (as a later photo here suggests). The text on the base looks to read 'U.S.S. Enterprise Standard Issue Tricorder'
Next we get the 3D printing form of the 'Screen bezel, disc ejector glamour bar and buttons':
Here are 'clear SLA resin display glazing panel prints':
An 'early display support frame':
And the design of the door panels:
Now this photo of a 'PolyJet 3D print produced by the factory' reveals a couple of telling details:
First is the moire. It seems to be built into the panel itself (thus seemingly dashing the idea that the moire is a removable data disc).
Second is the lower compartment. The 'drawer' seems to be deep in the front and shallow in the back. In the photo below, blue indicates a regular rectangular 'drawer', where the red indicates the actual shape of the 'drawer':
This photo shows two 'different rapid prototyping capabilities':
The Tricorder prototype on the right indicates WHY the lower compartment 'drawer' is oddly shaped. To accommodate the battery (red):
This makes sense, as there is a power port built into the rear of the case, right behind the battery (as seen in a prior Update photo):
That definitely confirms what Chris had previously written about a much more sizable and robust battery being used on this replica. In fact, looking at the trio photo again, one gets the impression the battery inside the Tricorder is close to the same size as the handle to the Phaser.
And given the weight of such a battery, this placement also makes sense for weight balancing of the Tricorder. Anywhere else and the replica would end up being top heavy and prone to wanting to topple over rather than sitting solidly when one places it on a table.
One other thing to note about the above prototype is a small metal plate (blue) below the battery (red), which is likely needed for the base to magnetically 'hold' the Tricorder.
The final picture is of 'laser-cut sheet aluminum side plates and a Mutlit Jet Fusion side panel' for fit testing:
As a wrap up, the Update identifies the "Coming Next Time": "Functional blocks - working out how it will work"
