Material of the DIY Sequential Shifter

LASER CUTTING

I recommend stainless steel.

3D PRINTING

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 PRINTING

You can buy a 3D printer, or find a 3D printing service like treatstock.

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
