... its the combination of the 3 "slanted" bearings, what's propagating the filament, when rotating

So ?
Where is the hot end, and all the rest ?
Seriously, I know how this "works", not a new idea. What would be new is a working and if possible better extruder !
Someone who boasts: "Very repeatable, and accurate to 125 nanometers (16 microsteps and a 1.8 degree stepper. 62.5 nanometers with a 0.9 degree stepper)." better proves it !

A piece of paper, a pencil, and some trig tables will confirm the figures. Or maybe you can even use a calculator?

Just a passing thought: Is it possible that this would work with only two wheels? At first blush, this sounds silly as the filament would pop out sideways as very under-constrained. However, the sideways force may possibly be easily constrained with guides if they were slippy enough or maybe with guide bearings just beyond the ends of the drive bearings. The question is, how big should the wheels be? There would be no sideways force with infinitely big wheels but perhaps 20mm is close enough to infinitely big for our purposes.

Do you have a screenshot of the updated design? I've been mocking up some simple experiments using 10deg pitch with some 683zz bearings and heatshrink to provide friction, I'm still dialing in tolerances on my design/print.
