A crown gear and pinion
thingiverse
A gear system utilizing a crown and pinion arrangement enables a 90-degree directional change in rotation. This diminutive gear pair boasts compact proportions: the pinion measures approximately 12mm in diameter, while its counterpart, the crown gear, is roughly 36mm across. Although scaling can be accommodated, as long as both components are augmented uniformly, this design was purposefully minimized to cater to intricate model designs. The pinion's integral features include a 3mm-diameter shaft hole accompanied by a boss for a set screw with an M4-40 thread, primarily utilized in educational gear sets. However, its usability is limited due to fine-toothed dimensions, making it less suitable for substantial load-bearing applications.
