Mini Watch Cleaner

Mini Watch CleanerMeet the Mini Watch Cleaner, a compact, 3D-printed machine designed for cleaning mechanical watch parts. This device features a few crucial components - most notably a continuous servo (geared up for sufficient RPM), an Arduino Pro Mini controller (for reversing spin direction every 5 seconds), and a small 4-digit LED display that shows a countdown and offers simple user interaction through two buttons. Below is an overview of the design, assembly notes, and usage instructions. Base & HousingThe base is a sturdy, cylindrical piece that attaches directly to a small glass jar measuring approximately 90 mm in height with a 65 mm lid diameter.The housing includes compartments for an Arduino Pro Mini, a continuous servo, the gear assembly, and the small LED display.The design is meant to “screw onto” or clamp down on the jar for a sealed fit when operating the cleaning cycle.Motor & GearingA continuous servo is used as the main driver. It is geared up to ensure an adequate
