Gear O'Clock - number plates and couple of changes
thingiverse
To create two plates for odd and even numbers, I replicated VeryWetPaint's accessory design but rotated their open top mechanism housing and main drive gear by 180 degrees in the Z direction for seamless printing using Slic3r and Skeinforge. The clock plates were scaled at x20 and x25 to fit my RepRapPro Huxley, which accommodates VeryWetPaint's ClockBaseDiv4 STL file at a maximum size of x25. I also modified the slotted drive gear to suit circular push-fit minute shaft clock movements from www.ClockParts.co.uk. For number printing, follow Stephen Cropp's method of splitting GCode for multicolour prints or opt for a 100% plastic clock with no paint. When scaling the numbers plates, ensure they correspond to the main dial and drive gear's scale factor. The only pre-scaled STL file is the main drive gear with a 3.6mm push-fit hole, designed for a x20 scale clock with approximately 8-inch diameter number gears.
