3D Printing the body and magnet holder

The body and magnet holder file are available in STL file format and can be printed with a resin-based 3D Printer. Part thickness is down to 0.3mm in some points, but it still printable, and after UV curing the part is strong enough.

Assembling the magnet holder

Once you have 3D printed the parts, it is necessary to assemble them. This video shows how the different components of one pin are assembled for the current prototype.

Coil winding

I assembled a simple machine to automate the coil winding. It is controlled by an Arduino.
