Magnetic, detachable key ring
thingiverse
I need an RFID badge, which I attached to my keys, to open the door to my company's garage. This means I have to turn of my engine, open the door and restart my engine every morning to get into the garage. To solve this, I designed this magnetic detachable key ring. Now I can easily detach my badge from my keys. Instructions Print both parts, then glue a disc magnet on top of part A and one inside part B. It's designed for 2mm thick disc magnets of 6mm diameter, like these http://www.supermagnete.ch/eng/S-06-02-N?img=1 You can also find them on eBay http://www.ebay.com/sch/i.html?_odkw=neodymium+magnets+6x2&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xneodymium+magnets+6x2mm&_nkw=neodymium+magnets+6x2mm&_sacat=0 To glue them in I used epoxy, but good CA-glue (superglue) may work too.
