Snake Keychain (remixed)

This model was created from scratch, based on the previous design by Cisco. There are several crucial changes:

• Profile is changed to an octagon and meant to be printed horizontally, lying on a print bed, so the chain can be longer. You can add or remove links right in the slicer.
• The first and the last link holes are now compatible with the carabiners on one side and the key rings on the other (all necessary supports are included in the model).
• Most of the sharp edges now have fillets or chamfers to make it less clinging when you put the keys into a pocket.

I tried to increase the tolerances to make it more flexible, but this type of chain has its limitations. If you need something more flexible, give the Franko Keychain a try.
