Key Fob / 3D Demo Print - Interlocking rotating gears

thingiverse

Two STL files are available for download, one accommodating a key ring and the other being a single print interlocking gear. The design consists of an inner gear, six central gears, and an outer ring featuring teeth that all turn together. A total of seven separate-looking inner gears work in harmony as part of a single, integrated system that does not come apart. This unique configuration allows each gear to rotate synchronously with the others. The possibilities offered by 3D printing technology are clearly evident in this fun and functional print. Instructions for assembling the piece emphasize careful clearance and material thickness, suggesting an optimal resolution and density suitable for most 3D printers. Following standard 0.20mm layer resolution guidelines with a 50% fill setting can achieve desired results. After removal of any unwanted extruded support structures from underneath, examine each gear individually to verify its ability to turn freely without compromising the mechanical link between them. To confirm that all gears function smoothly in tandem, apply gentle turning motion while ensuring proper fit and engagement throughout each set. This piece was specifically optimized for use with a Replicator 2 and shows potential across various printing platforms with moderate effort during preparation and finishing phases
