Day of the week clock
thingiverse
A timepiece that distills the hour-hand movement from a standard clock and compresses it to 1:14 through clever gearwork. The clock face measures 220x220mm, making it easily printable on an Ender 3 3D printer. To accommodate a filament change, pause around layer 8 and swap the white plastic for black or another color of your choice. Two M3 screws are needed to secure the mounting posts that support the large gears. The clock's mechanism is a generic one sourced from Amazon, boasting an 14mm (8mm diameter) shaft. Update: As of April 5th, 2020, I've made two key adjustments. Firstly, I corrected the "main gear mount" to include a screw hole. Secondly, I tweaked the second gear mount, widening its screw hole to 3mm from the original 3.2mm diameter.
