Not the last one, the latest one.

This is a new version of http://www.thingiverse.com/thing:1613943. I changed the desigen a bit and I split the "key holder_1" in two parts, so I dont need any support material to print the parts.
The parts "key holder 1A" and "key holder 1B" are glued together and screwed to "key holder 2" via three round spacers. I have used these round spacers (https://www.hstronic-gmbh.de/Abstandsrollen-Messing-vernickelt-Innendurchmesser-26-mm-fuer-Gewinde-M25) and cut a M3 thread inside.

There are two versions of the key organizer.

The first version is for up to nine keys and the second version for up to five keys.

Parts for version one :
3x round spacers L=12mm, 1x locking disc_9 keys.stl, 1x key holder_1A.stl, 1x key holder_1B.stl , 1 x key holder_2.stl , 1x keychain.stl and spacer.stl to prevent the rattle if less than nine keys are installed (For example 2 spacer if you only have seven keys).
6x M3x6 countersink screw (DIN 965) , 1x M3 washer.

Parts for version two :
3x round spacers L=7mm, 1x locking disc_5 keys.stl, 1x key holder_1A.stl, 1x key holder_1B.stl , 1 x key holder_2.stl , 1x keychain.stl and spacer.stl to prevent the rattle if less than nine keys are installed (For example 2 spacer if you only have three keys).
6x M3x6 countersink screw (DIN 965) , 1x M3 washer.
