I knew I was going to get to a point where I wouldn't know how to go about modelling the rest of the enclosure / skeleton, but I modelled the section that I could.

This all started by first looking on JLC for prices in MJF and SLS, mainly how big could I go until I was charged more than $1/part. It seems that adding a 1.5mm thickness to the pressure plate (for a Tetrinsic that's got nothing fancy happening like a solar cell or LCD) is where I go over $1, and by a good 40% increase. It's probably best to just keep with the normal pressure plate and then stick a 1.5mm peice ontop as then a vast array of colours and finishes are available for the visible part of the Tetrinsic.

And these are the other parts:

The reason why I'm trying this is partially because I'm trying to think of a solution to actually holding them in place in the Proof Of Concept Tetent, which is almost the same as the fully featured one except that there's no battery and would only have 2 out of 4 Memory In Pixel LCDs.

The second is to allow easier integration into custom hardware designs.

Anyway, if all 3 parts were printed for 10 Tetrinsics, it'll cost £31.60 though I'd assume the shipping price would be bundled if also fabricating the PCBs though JLC too:

It'll look something kinda like the below, but this idea will only work if I somehow think of a way to mount the PCB.

Speaking of the PCB, I've been looking into panelizing 4 into a 50x50mm area as I hypothesise that I could get 20 boards (4 x 5pcs) cheaper than 10 boards (1 x 10pcs).
