Filament sample links that are designed to attach to one another. Two versions available - one with snap in links (5), another where you can use a filament hinge to connect (7). I ultimately wanted to make a design that could be “plug and play.”
One of the issues I had with filament samples in general is keeping them in one place that can run out of room. These can connect to make an infinately long chain!
Also a mini tolerance test ;)
No supports needed for either version.
Suggested print settings - 0.4mm nozzle, 0.12mm layers
