The latest innovation is the development of the servo mount is the addition of a manual switch that can be used before the track is automated.
A new 3D printing material has been used – PETG. Some black PETG has been sourced and has been used to make this mount. It is the same material that is used for plastic bottles. The print head runs at 230 degrees centigrade but the resulting mount is much tougher.
At the far end of the track, the pile of magazines supporting one end of the track has now been replaced with a timber support.
