About this 3D model

A small boom crane for Brio, Ikea, or other wooden trains. It is based around a standard 150mm section of straight track. Hardware required for assembly: 3x M3 screws ( I used 6mm, 15mm, and 20mm, but the lengths required are fairly flexible) 2x M3 washers A small compression spring A 10mm diameter magnet The spring and pin are not strictly necessary, but they help keep the crane in position under heavy loads.
