Rotary adapter

thingiverse

This is a versatile adapter that allows you to combine one rotary encoder and two push buttons into a single splited knob. You can customize it to meet your specific needs by selecting different components, such as using one rotary switch with an encoder or two encoders together. Various types of rotary switches are available, offering distinct detents and center configurations. With this adapter, you can easily combine the perfect switch for your application with a rotary encoder and push button (if needed). It's designed to accommodate common, affordable parts that can be found in most markets. One potential use case is in radio control systems, where turning the outer knob adjusts frequency, while the inner knob controls volume, and pressing the inner knob switches the radio on or off. You have complete freedom to design your own configuration, omitting any unnecessary components if desired. If you find this project helpful, consider treating me to a cup of coffee as a token of appreciation. Print Settings: Printer: Anet A8 Rafts: Doesn't Matter Supports: Yes Infill: 25% Notes: Base.obj requires support only for the tray (not everywhere). The rest of the objects do not need plate support. Post-Printing: Gears and Shafts I designed the gears to match perfectly with encoders and switches featuring different shaft shapes. To prevent gear slippage, apply a single drop of super glue after assembly. Base Object The base object features several holes for securing the separator and back cap. Refer to the accompanying image to understand their purpose. You can use small bolts and nuts or tireups for this purpose. I used tireups from the opposite side in my photos solely for visual clarity. Preventing Gear Jumping For the inner shaft, occasional gear jumping occurs when turning quickly or under stress. This issue is easily resolved by applying a tireup around the entire base. You'll need long tireups or multiple connected ones for this purpose. Avoid passing them through the base and instead circle it with the tireup. Lubrication will further enhance performance, but be cautious not to overtighten. How I Designed This I didn't design this adapter solely because of its functionality; rather, I addressed a problem that often plagues makers: finding specific components can be challenging or expensive. For instance, a Mechanical Dual Concentric Encoder is pricey, whereas combining a rotary switch with a specific number of detents and centers along with a rotary encoder is nearly impossible to find affordably. This adapter provides an affordable and convenient solution, offering the added flexibility of incorporating a button if needed. Custom Section Ensure all touching parts are lubricated for smooth operation. Create Your Own Knobs After assembly, create your own knobs by utilizing the circular shafts available. It's the easiest part of this project.
