[M] Sculpting a look

A project log for Tetrinsic [gd0041]

A continuous, motorised slider that is force sensitive, haptic, UV self-sterilising and water resistant.

This is essentially how I imagined this curve would go… ish… it's kinda boxy though.

I've also moved the strain guage right to one side so that I have space for some kind of linear slider. I need 33mm and since the total length target is 70mm, I might as well say I need half that (35mm). 
Ok I've made some arbritrary-angle cone because chamfering a solid cylinder wasn't working. Why I'm using the bounding box to sculpt how I want the exterior to look, I don't know.
THAT'S IT RIGHT THERE. The magic of the Delete Faces command.
Changed the bounding box to white and edited the LCD image for more contrast and this looks SWEET.

Maybe now all I have to di is add a filleted chamfer on the end?

This 100% looks like a shoe though, or some robot leg that's been cut off.

Move the motor forward so that the tabs don't stick out...

Add the chain back in...
...and adjust render settings...

That LCD background I found certainly gives off the "new age" and "powerful inside" vibe I wanted to see for Tetrinsic.

Next week would actually mark the 1 year anniversary of conceptualising Tetent using the OG Tetwin Switches. From that, which only had manual force adjustment, per-key RGB and 5 discrete double-action switches (which meant that I needed 3 fingers for 2 characters), to Tetrinsic that dropped LEDs alltogether and had non-simulated strain guage mount geometry but added in a BLDC motor so that #Tetent Turntable [gd0038] could be scrapped and Tetent could physically move my fingers to where they needed to go whilst learning, to now with Gen 3X1!

I feel like an Apple executive when I say this, but Gen 3X1 is the most customisable and easy to maniufacture Tetrinsic yet. Probably more reliable too now that I've seemingly managed to fit a relatively low cost aluminium load cell that are built to much higher specifications than I'd ever be able to 3D print. The 'keycap' material has been upgraded to stainless steel, 16MB of flash storage for LCD animations and a 33% active area length increase are all improvements from the first Tetrinsic design that I was almost about to build. I'm a bit more sold on the look of Tetrinsic 2.0, but this concept looks MUCH better than the first Gen 3X1 concept. 

There's just a price hike, like what NVIDIA's done with 4000 series. At least someone could build a 4-finger Tetent for about £100, which I believe is in the realm of affordability for people that have a lot of digital work to do for their forseable futures..

Multiple Tetrinsic's together also looks pretty good actually. It looks more store-bought than I was expecting. I'm wondering if I should make 2 versions where the strain guage is on either side so that I could actually just slide Finger5 forwards instead of the tightly-packed Fingers2-4 backwards.

Oh wow I could actually do that without an intersection? Shame I can't find anywhere to put a 5th Tetrinsic. Well... I could put it along with the others but I don't know if my hands or pockets would accomodate 100-110mm and I don't know of Tetrinsic could accomodate some swivelling. It's probably possible but likely requires the knowledge of whoever makes those Autobot Transformer toys. If that was the case, the TimerSpy could be symmetrical like what I was doing in #Tetent [gd0090].
Solution mining... ends, in 25 days.
