Automatic Door-closer (mechanical)
thingiverse
This is a simple system to close your doors automaticly. It could be used indoors, in the garden or on a fence - feel free. Also it is fully mechanical and needs no electronics. Parts you need in addition: 1 bearing 606ZZ (maybe I will add a impeller without a bearing - it should work too) Some weights (Sand, leadscrew, or something thats fit in the cylinder) some glue to close the weight-cylinder some screws for mounting a strong cord Notes: If the impellerholder isn't used to lead on the left side of the door, you can mirror it in your slicer-program. UPDATE: 2016-11-05: Function Report: Now that I have this thing some days working, I have to say it works perfect. The cord never left its guidance and the door shuts like it should.
