Parametric solenoid spool
by caru, published
This is a spool, developed in OpenSCAD, that can be used to build a solenoid (aka electromagnet) with enameled copper wire. It has two holes on each base, used to insert the wire and to hook it once the solenoid has been rolled. The wire can also help to keep the two pieces together, but I am not sure if that will be enough. Probably gluing them together is safer.
Of course, it can also be used as a generic spool for any kind of wire.
You can modify the following parameters:
i_diameter: the internal (core) diameter
o_diameter: the outer diameter, on which the solenoid will be twisted
i_height: the internal height between bases
base_diameter: the bases diameter
base_thickness: the thickness of the bases
in_hole_offset: the offset of the first hole, where the wire will enter
out_hole_offset: the offset of the second hole, where the wire will exit
hole_diameter: the holes diameter
wedge_height: the height of the wedge
wedge_thickness: the thickness of the wedge
solenoid(14, 18, 50, 50, 4, 12, 20, 4);
translate([51, 0, 0]) base_only(50, 4, 14, 18, 13, 20, 4, 8, 4);
Thanks to all the guys in #reprap IRC for their suggestions!
- Print printable.stl (or generate a custom one like in the example above)
- Assemble the two pieces (and optionally glue)
- Roll the wire(s).
- (optional) Fill the core with metal rods and glue
- Give it current.
