Magnetic Detachable Keychain

Here is a nice way to detach your key or whatever you want !
I use this print to clip and detach my motorcycle's key every day!
Hope you will enjoy it!

I add a brim (2mm) in program to solidify the hook on the tray.
I add also a pause in program to put magnet. 

Dimensions of the magnet :  8mm diameter - 5mm of thickness

(of course, you can also put 5 magnets of 1mm thick, etc)

Enjoy!
