Vertices: 1.1kMore model information
A simple modification to enable the old style ESU 51900 decoder tester to have its DCC sound speaker switched on or off. As manufactured, the speaker is always on, which is not always useful for testing.
To complete the project, you also require 3mm OD wire, soldering equipment, a 1.8mm drill bit/drill, superglue and a 2-way (On/On) miniature slide switch of the following dimensions: 10.50 x 5.70
Designed for standard PLA. 100% fill. Support recommended.
