Shuttle Saver

Print in TPU with the inset upside down (vents against the print bed) - no support required. Hydrate some orbeez for 4+ hours, fill the inset with them and cover with the outer part. Replace the plastic cap at the cork end of your shuttle tube with the Shuttle Saver and let the orbeez magically hydrate your shuttles, making them last longer! Original inspiration came from a commercial product - humidome, but I wanted something cheaper and simpler.
