I've been modelling for about 3 hours (and it's now 3am), but as you can see, the only noticable difference is the fact that the ball chain is now visible and that there are actually slots for them, instead of just phasing through walls. The reason for this modelling time is because of Tetrinsic. Sourcing solid 1.5mm rods is more expensive and not as available as 2mm (on AliExpress) and I'm not too fond of the 2.0 safety rating from the 500g force simulation. Long story short:

• To keep the minimum wall thickness of the pressure collector as 1.2mm, I had to model slightly different geometries for the center and side rods and move the load cell up 1mm.
• The new rod configuration had to be applied to the pressure collector geometry.
• I then had to simulate it again, and I've got 3.2 safety rating in a tiny spot and 4+ everywhere else.
• I get 0.33mm of displacement, which balances out the increased rod size, allowing me to keep the 5.2mm offset.

Now all I have to do... is turn this concept into a reality. While I'm saddened that this device is so large, I'm glad that it actually looks so minimalist despite trying to be as good or better than 6 seperate input devices and be sustainably powered. I even watched an hour or two of artists drawing (both digital and paper) to better know what motions are usually performed.

I'm sure some mathmatician or engineer has said "something something simplicity something complexity", or something, like "the most beautiful equation" being e^(i*π) + 1 = 0. I doubt it was even remotely as simple as it appears to actually discover that equation.

The next step I would like to do is see if I can print a concept with sliding peices to better understand mounting positions and ideal screen locations.

I've had to increase the squares to have sides of 40mm, but it also means that I can have a 2.4mm roof over the Thumb Tetrinsic whilst having its square touch the ground (no hovering or extension necessary". I've also thickened the white section from 5mm to 7mm. I think, after all the setbacks since discovering the turning radius issue of the 3.2mm ball-chain, I'm finally onto a winner here. You know, some "we're so back" energy.
