Material of the DIY Sequential Shifter
LASER CUTTING
I recommend stainless steel.3D PRINTED SEQUENTIAL SHIFTER
As for the H Shifter, I recommend PLA or ABS. You can apply 20% infill for all parts except for the part Spring Support – Quantity 1.stl, for this one I recommend 80% or 100%. Here are recommendations for printing 3D solid parts.
HAND CUTTING AND CNC MACHINING
I recommend aluminum because it is a soft metal that is easy to work with.How to get the required materials
LASER CUTTING
I advise you to request a quote from laser cutting companies near your home. All parts are flat with 5mm thickness, there are none to bend. So you can compare prices and choose the most profitable. You can save money if you make a combined order. For France and Europe, I recommend the company ALPM, and they provide a very good quality cut for a reasonable price.3D PRINTED SEQUENTIAL SHIFTER
You can buy a 3D printer, or find a 3D printing service like treatstock.
Looking for high-quality 3D printing services? With Treatstock, you can easily get instant quotes from professional manufacturers worldwide. Upload your design today and get your free, no-obligation quote in minutes! 👉 Get Your Quote Now
HAND CUTTING
You need only sheets of papers, printer and Aluminium plates!CNC MACHINING
I recommend CNC Machining only if you own a CNC Rooter, otherwise it is not economically profitable enough compared to laser cutting.SCREWS
Bolt depot, Motedis and FixnVis.Tolerances
- Laser cutting DXF files and CNC Machining files: 0.2mm
- 3D Printing: 0.6mm
does not feel right it is too stiff, and you do not feel the shift at all
Hi AlWaheeb,
We’re sorry you weren’t satisfied with the Sequential Shifter.
However, with proper adjustment of the stops and spring stiffness, you’ll be able to feel the gear shifts perfectly.
Best regards,

Très bon projet, en cours de réalisation
I built both the handbrake and the sequential shifter, and overall, I quite like them. I didn’t read the instructions closely enough and I purchased the wrong springs, but once I corrected that, I was quite happy with the performance. The designs are simple and effective.
My biggest complaint is the tolerance between parts; everything has a 0.6 mm gap, which seems quite excessive to me. I was able to redesign the “fixing parts” (which attach the controllers to the frame) with a .2 mm tolerance, and that works quite well, but reprinting the “fixed parts” and “mobile parts” with a 0.2 (or even 0, for connecting the moving parts) tolerance is more challenging, since it would require editing an STL rather than designing a simple square piece. For my convenience, I used 3d printed spacers with heat set inserts instead of threaded metal spacers, and that works fine.
In the end, though, I spent roughly $60 US on the plans and parts, and got a sequential shifter and handbrake, both of which work as expected, even if they are a bit loose and sloppy.
Thank you for taking the time to make these designs, and I’d love to see a revision that reduces the parts tolerance!
