Three Jack-o'-lantern keychain designs that can be printed with a multimaterial system like AMS or MMU2S or in individual parts to be glued together in case you don't have access to those systems.

The keychains are split in half and need to be glued together. This ensures it prints perfectly without supports and that the holder for the chain is printed in the strongest orientation posible.

I have used in mine eyelets (5mm diameter for the passthrough part, 9mm exterior) preventing any wear to the printed part. I have been using this system for a long time and never had a break so I encourage you to do the same.
