G Scale Coupler

I designed this G scale coupler after running out of the LGB and Aristo Couplers. Most of it is 3D printed but a few parts are not.

The non-printed parts include a 0.3mm Wire Dia, 2mm OD, 10mm Free Length Spring, a m3 12mm long bolt and a nut, and finally a piece of 1.5mm wide or 16 gauge wire for the cut lever.
