What is this? A gym for ants? Just kidding! It’s our latest 3D print project: a 2cm diameter kettlebell. It’s super small but packed with detail. Where would you put this? On your desk? On a keychain? In a miniature display?

This model is a screw-in silica gel container designed as a replacement/upgrade for the original spool screw used on Universal Spool [Diameter & Width Adj.] AMS Ready Once installed, it allows you to place silica gel granules inside the spool, helping to keep filament dry and reducing issues caused by humidity such as stringing, bubbling, and poor layer adhesion.
