[15:30] First, I actually sketched a 1:1 with a pencil what I was going to model. I don't usually do this.

The main ideas is that there are 2 displays (since other Tetent devices would have one one each half anyway) and Finger5 would be shortened so that the finger doesn't hit a corner. I was also considering a 21700 battery, but the screens are 26mm on a side so the 26650 makes the most sense.

Well I started modelling and the geometries were lining up in different ways (this is the reason why I usually don't sketch) and Finger5 actually goes straight over the top of Finger4.

After modelling, I tried a dual tone thing but I think plain white looks better:

But 🎉🎉🎉 finally, after all these months, I've finally got a concept render for this project. Shame it took an hour to sketch and another 2 to 3D sketch.

The dimensions are around 220 x 82 x 30mm which unfortunately isn't all that small but looks kind of slim actually. It might also get larger if Finger5's ergonomic movement line doesn't line up with the Tetrinsics modelled above.

Thankfully, it means that Tetrinsic Gen 2X2 is good to go.

[22:45] I've now determined where the USB-C port is going to go. I wanted to avoid pointing out of the bottom because that would prevent being able to rest the device on a table. The top was also occupied, thus I decided for it to go somewhere on the back and I've gone for the top-back so that conflictions with straight and 90degree cables were minimised.

The reason why the USBC cable is orientated portrait is due to the 90degree cables, which are the ones used in #Teti [gd0022] for the portable monitors.

Hopefully, there should be enough remaining space for the 26650 to squeeze in.

I'm also thinking that this design might still be usable with one hand if the large flat side is placed on a desk and used with a similar grip to a mouse.

I've also removed the bezel inbetween displays and I now think it looks rather good from the 1st person perspective:

The screen itself looks rather nice too, and I can imagine a nice 60FPS boot animation (inspired by PS3) that will be similar to how I plan to do the #SecSavr Sol^2 [gd0045] startup animation (that I haven't yet gotten around to making).

Here's what it would look like with an iPhone X and 14 Pro:

Part of the thumb's job is to keep everything held stable, which means it's better if the centre of gravity is on the thumb side. That way, the thumbs can just apply a force to counteract the fingers and the phone can just rest ontop of the thumbs.

[17 March] Another render:

This design is now seriously being considered for Tetent (gd0090).
