16mm Narrow Gauge magnetic coupling

thingiverse

A simple 2 piece design of buffer and coupling base. Simply add a 6mm magnet into the hole, and secure with a dab of super glue. The single magnet couplings are "handed", so you will need to make one North and one South, and each wagon or coach will only be able to couple up the right way round. A dual version using 2 x 3mm magnets is included if your stock gets rotated in use. To secure the 2 parts together, use a small screw. Leave some slack, so that the coupling can move from side to side and up and down, as this will reduce the chances of the coupling lifting a lighter wagon if the height is not identical. Can easily be printed in PLA on a standard printer without supports. Use 0.12mm layer height to get best finish.
