There are two versions of the key holder.

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

Parts for version one :

• 1x key holder_1.stl , 1 x key holder_2.stl , 2x standoff_9 keys.stl , 1x locking disc_9 keys.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). 3x M3x20  countersink screw (DIN 965) , 3x M3 locknut , 1x M3 washer.

Parts for version two :

• 1x key holder_1.stl , 1 x key holder_2.stl , 2x standoff_5 keys.stl , 1x locking disc_5 keys.stl , 1x keychain.stl and spacer.stl if needed (For example 2 spacer if you only have seven keys). 3x M3x14  countersink screw (DIN 965) , 3x M3 locknut , 1x M3 washer.

The part key holder_1.stl needs support. I printed key holder_1.stl and key holder_2.stl with HDglass from Formfutura and 0,175 Layer height, for the standoff and the locking disc I used ApolloX from from Formfutura but you can also use ABS.
