I'm pretty sure this weird little plugin only appears in one episode - and for all of 10 seconds - but it's Tricorder-related, so I have a need to get involved.
It slots into the scanner pocket and contains two little plant-on face greeblies:
I think these went on to become the headband version of the cortical stimulator.
A Japanese collector has a good set of reference images of the original:
I decided to make use of having lots of 3D printers at my last job and model this up quickly - I've only ever used SketchUp and it's not great with curves for the most part, so this wasn't exactly easy! I note on the original it has flat sides rather than the curved edges of the Mk VII so I was more than happy to copy that rather than try to design something that looked like an organic extension of the very rounded Mk VII (you can see that the original wasn't exactly the best fit).
I put my MT in my scanner in order to pull the dims and crucially match the top curve of the MP section...
...and a few hours in SketchUp later I had this:
I then gave this to our concept artist who actually knows how to set a file up for printing, and about 24 hours later it was done:
This ended up being about 1mm too big to fit in the scanner pocket, which meant lots of sanding (not sure what it was printed in... but this took a while). I've got the majority of lines out of it, but I think i need to hit it with some filler primer, or, worst case, some actual filler (I hate filling). I also sanded in a radius to the side sections, and I'm pleased to report that mine lines up as badly as the original
The next step (other than filling) is to insert a magnet into the scanner section to align with the magnet already in the Stapleton tric to hold the scanner in place, and do the plant-on sections from styrene. I'll probably do these by hand rather than get them laser cut.
After that, I'll move onto the stimulators (or synchronisers as they function in the ep). Not sure how they were stored - it looks like Gates really pushes the plugin into the MT body and then has to hold it in place to get the synchronisers out. I'm guessing they were friction fit which probably isn't sustainable for a display piece so I need to work something out - maybe some foam pads as per the satchel medkit. Don't want to get too involved with magnets as I don't want to hollow out the lower section too much - if something goes wrong with that, it'll be no fun filling in down there.
Does anyone have any ref/info on this thing?
