Learning clock with planetary gear
prusaprinters
<p>Clock for kids - they can turn minute hand and the hour hand turns as well exactly as on real clock. Children can learn the planetary gear as well :-)</p> <h3>Print instructions</h3><p>Print all the files except <code>clock_donotprint.stl</code> (this is for reference of complete clock only). <code>planetgear.stl</code> is required twice. I printed it from PETG using 0,2mm layer and 0,4mm nozzle, but the print is easy - no supports are required. The dial is printed "face down".<br/> Assemble the gearbox first (image), then put on the dial and finally click the hands (no glue is neccesary).<br/> You can make paper "cover" on dial depending on your children skills (e.g. 12/24 hours format, minute numbers).</p>
