Description
A 3D printable shaker-style keychain inspired by gym protein shakers, designed to create a realistic sound effect. By inserting a small steel ball during the print, this mini shaker produces an authentic rattling sound, making it a fun and unique accessory for fitness lovers.
When using my print profile, the print will automatically pause at layer 220. At this moment, you can choose to insert a small steel ball (I used 8 mm steel ball) inside the shaker (or a little plastic cylinder), then resume printing to achieve the realistic sound effect shown in the videos.
