.25mm tolerance gyroscope keychain

myminifactory

Here's a compact gyroscope designed to work seamlessly with a keyring, consisting of four concentric rings connected by a durable loop that ensures secure attachment. Each ring is carefully spaced with a precise tolerance of 0.25 millimeters, and for optimal spinning performance, it is recommended to print this model using FDM technology at a layer height of exactly 0.1 millimeters. Edit: The t_300um file contains an identical gyroscope but with a larger tolerance of 0.3 millimeters, making it suitable for use in printers that may not have the same level of accuracy as the Ultimaker 3 I used to print this model.
