[MOC] The Most Ultimate Sequential Gearbox

[paave]

I've been thinking of a simple yet effective sequential gearbox for a long time, and since LEGO had released a 18T clutch + 14T gears, I've come that now it's possible to partially reveal it

It's a kind of successor of the Anto's 6NR gearbox 

The main difference is that there are no multiplier gears. There are straight up-down transitions connected left-right with equal gear ratio. With the current 6 clutch gears existing, it's possible to make 6 speeds, but to fit the 15x11 frame, only 5 speeds for now. There are still no studio files for new gears, so I used 16 gear recolored. The orange is 18T clutch, and the white is 14T. The upper 16T gear - axle - is connected to engine, the yellow connector - to wheels, the red connector - to turn drums on 45°

It will be possible to create 8 speed gearbox (or 9 with specific drums?), when LEGO release 14T clutch + 18T, 10 clutch + 22T, and 22T clutch + 10T gears. If someone can design these parts for 3D print ready, that would be nice

All the possible gear ratios:

1. 8/24 = 0.33
2. 10/22 = 0.45
3. 12/20 = 0.6
4. 14/18 = 0.77
5. 16/16 = 1
6. 18/14 = 1.28
7. 20/12 = 1.66
8. 22/10 = 2.2
9. 24/8 = 3

I don't have all the gears needed now, but with what I have, it works well

You can use this gearbox wherever you want and I wouldn't mind to see it in the future ultimate set with probably different drums
