Zupčanik poklopac – 3D štampano

Accessorize the light switches at your home or office with this intriguing mechanism that utilizes a planetary gear! All parts can be 3D printed (no supports are required), and the design is fully snap together – so no glue is needed.  I printed the five gears as a unit (using the attached “Planetary Gears.stl” file), which shows their proper orientation for assembly.  But, if you’d rather print the gears independently (or are worried that a roughly .2 mm gap tolerance between the gears may cause an issue on your printer), then an individual STL is provided for each gear as well.I designed this model from scratch for the “Office Accessories” here on Printables, but I want to call out “Engineer Dog” who showed off a similar idea several years ago.  Some notes on assembly
