I haven't been able to wrench lately, so as part of my isolation I'm creating a working full size 3D printed model of a seamless shifting 2009-2014 F1 Gearbox. It's been quite the undertaking and it's still in progress but I thought you all might find it interesting to see how a relatively modern F1 gearbox actually works.
I also built a 3D Printed Sequential Shifting 4 speed Dogbox as well if you're interested.
