NASA chainmail inspired keychain. Perfect gift or handout to showcase interlocking parts in 3D printing. The easy to use yet secure clasp also doubles as a place to hold and spin/fidget the thing.
Print preparations:
Filament: Use dry PETG or similar tough material. PLA also works but don't expect it to last as long in rough use.
Bed adhesion: Bed adhesion is critical for this print. I use Cool plate SuperTack for PLA and PETG without issues and suggest you do too. If using PEI plates, prepare better than ever: clean with detergent and brush, use brush also when rinsing well, careful use of adhesives etc. Monitor the print and try again if at first you don't succeed. You and your printer can do it!
Removal: Detach the finished print carefully with a scraper. Don't be tempted to rip the whole thing out from its end. For SuperTack, remember to keep the bed warm (~40'C for PLA, ~50-60'C for PETG)
Break-in: The links might be a little stuck at first. Loosen them up by moving adjacent pieces back and forth two at a time. Don't twist and bend the whole thing yet to avoid causing excess stress. Once all the links are loosened up and wiggle around freely the thing is quite flexible and the stresses distribute among the links.
