Update (22/10/2020):
The following parts were updated (printing default orientation and support optimization):
SPRING SUPPORT_1;
SPRING SUPPORT_2;
KNOB_EXTENSION.
Update (17/06/2020):
The following parts were updated/added (mainly tolerances):
LOGITECH REPLACEMENT PART;
SPRING SUPPORT_1;
SPRING SUPPORT_2;
ACTUATOR_1;
ACTUATOR_2;
KNOB_EXTENSION (Still want to design 2 more with different heights (specially for H pattern use)) .
To lock the knob, you will need a M4x40 screw!
--------------------
Decided to create a versatile sequential shifter mechanism, that could be easily installed on a Logitech G Shifter, depending on which car or game I wanted to play.
A simple rubber band or spring would a similar job ( (I had it installed on my shifter before), but I find the feeling/force of this mechanism more "realistic" and robust, and besides that, we have to make some good use of our 3d printers, right :) .
Although this is still a WIP design, it is already functional, so it should work just fine.
But some optimizations are yet to be done, so further development and community feedback will help with these points:
- Replacement Part Concentricity;
Overall Rigidity (might create a connection between both "spring supports") Wait for further updates ;)"; - Tolerances;
- Printability;
- Design a Knob extender.
You should be able to glue the existing boot to this new replacement part. I haven't tried it, so I cannot guarantee it will work.

- Tolerances: Make sure you are not over-extruding, or you might have to sand or force some parts into position.
- Supports: All parts should be orientated automatically when loaded to your slicer. The chosen position is the one I think has the best compromise between printability and performance. Make sure you add 1/2 separation layers between supports and the actual part
