Material of the Sequential Shifter

• LASERCUTTING

I recommend stainless steel.

• 3D PRINTING

I recommand PLA or ABS. You can apply 20% infill for all parts except for the part Spring Support – Quantity 1.stl, for this one I recommand 80% or 100%.

• 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

• LASERCUTTING

I advise you to request a quote from lasercutting 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, 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.

• HANDCUTTING

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 lasercutting.

• SCREWS

Bolt depot, Motedis and FixnVis.

Tolerances

Lasercutting DXF files and CNC Machining files : 0.2mm

3D Printing : 0.6mm
