Compact worm gearbox

This is a compact gearbox designed to automatize my chicken coop's door. Idea comes from an electrically foldable car mirror. Motor used is a recycled Epson printer, [Mabuchi-motor RS-445](https://datasheetspdf.com/pdf-file/813149/MabuchiMotor/RS-445PA-14230/1) on the axis of which I made a flat. This motor has a wide range of possible voltages 12 to 42V.
