Here I will explain to you how to make a DIY Sequential Shifter. It will be quite easy and quick to do. This sim racing shifter is strong, adjustable, easy and inexpensive to build.
There is almost no difference between the 3D printed version and the metal version (laser cut or CNC machined). The assembly will be almost the same. You can use this tutorial if you have opted for a steel/aluminium shifter.
Here is what I will help you achieve:

STEP 1: DIY Sequential Shifter Mobile part
To begin, we will assemble the mobile part.
![STEP 1 : The mobile part](https://www.diysimstudio.com/wp-content/uploads/2024/05/mobile-part-1024x576-1.webp)
The required parts:
![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/05_mobileparts-1024x836-1.webp)
Assemble the first plate. You must insert the screws and spacers, after that the bottom mortise, M8 Female rodend and its centralizers (red in the photos).

![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/06_mobile-build-03-1.webp)
You must then assemble the knob and its support by screwing it.

And finally, fix the second plate.

STEP 2: DIY Sequential Shifter Fixed part
Now we will assemble the fixed part.
![The fixed part](https://www.diysimstudio.com/wp-content/uploads/2024/05/fixed-part-1024x576-1.webp)
The required parts:
![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/07_fixedparts-1024x757-1.webp)
As with the mobile part, you must first make the fixings on a single plate. Don’t forget to solder the wires on the microswitches before sticking them (with glue) on their supports.

![Fixed part mounting](https://www.diysimstudio.com/wp-content/uploads/2024/05/07_fixedparts-4.webp)
Now you can finish fixing the second plate.

STEP 3: DIY Sequential Shifter final assembly
Now we will assemble the mobile part and the fixed part, as well as the springs.
![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/08_final-assemby-1024x768-1.webp)

![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/08_final-assemby3.webp)
You must now insert the M8x130 screw and the two springs, as well as the two nuts.
![Springs assembly](https://www.diysimstudio.com/wp-content/uploads/2024/05/09_springs_mounting1.webp)
STEP 4: Soldering
You have now completed the assembly, you need to move on to soldering. There are two solutions: Arduino Pro Micro and and 0 Delay Usb Arcade Board (the easiest, and used for the H Shifter).
For the Arduino solution, here is the soldering diagram:
![Arduino Wiring for the Microswitches](https://www.diysimstudio.com/wp-content/uploads/2024/05/Wiring.webp)
The Arduino Sketch is provided in the file.
- Arduino Pro Micro Board
- Micro USB Cable
- Arduino software: https://www.arduino.cc/en/software
- Joystick library (mandatory): https://github.com/MHeironimus/Arduin…
Here I will show you the solution with the 0 Delay Usb Arcade Board, which is easier and plug and play.
To begin, you must solder the 2 pin connectors to the microswitches. I used this Wire cable stripper and an Electric Soldering Iron.
![Soldering of the Microswitches](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_01.webp)

![Soldering of the Microswitches](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_04-2.webp)
The microswitches must be connected on the USB board.
![Microswitches connected on the USB Board.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_05.webp)
Remove the plate from the fixed part and remove the two microswitches supports.
![Removing the side plate.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_06.webp)
Now glue the microswitches to their supports. You will need to fit your microswitches onto the two small tips.
![Microswitches with the two small tips.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_07.webp)
![Microswitches fixing.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_08.webp)
![Microswitches fixing.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_09.webp)
You can now reassemble the microswitches. If you want avoid wires collisions, place the wires of the microswitch which is in front between the red mortise and the female rodend.

![Microswitches fixing.](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_11.webp)
Reassemble the plate and fix the USB board to the inner side of the plate.

![DIY Sequential Shifter](https://www.diysimstudio.com/wp-content/uploads/2024/05/soldering_seqshifter_14.webp)
You can connect your shifter to your PC and test the microswitches with the Windows game controller.

STEP 5: Adjusting your DIY Sequential Shifter
Now, you need to adjust your springs (using the nuts and tightening the M8x130 screw). In neutral gear, the mobile part must be straight (90° angle), and the springs must be slightly compressed. You also can adjust the range limit of the lever.

Congratulations! Your DIY Sequential Shifter is complete, you can now enjoy it in your favorite games.
