Case for speed control for train H0.

Casing for H0 analog locomotives or direct current motors from 0 to 36 volts and up to 2 amps, for H0 trains the maximum voltage is 16 volts and this can be limited with a 12 to 16 volt eliminator.
The casing can be printed complete or to save time and material, the stl files are divided into parts and then glued together. Assembly instructions are in the photos.

For the knobs of the potentiometers were used:

These PCBs were designed for the specific casing, for which they can be found at the following URL, they include the Sprint Layout files, Gerber and Excellon files, as well as the assembly instructions and parts of the PCBs (Spanish and English), as well like programming on the Arduino Uno. The Arduino was programmed on the original board and then removed to mount it on the new board.

The PCBs were made on a small CNC from a previous project.
