Plantronics CS 540 and 540A Earloop

The official replacement earloops from Plantronics keep breaking. Modeled this so that (A) replacements can quickly be printed as needed, and (B) replacements can be printed in a more durable material, such as PETG or TPU. The included 3MF files have the connector ring separate from the loop so each can be adjusted independently as needed. Also included the FreeCAD file where I modeled the loop portion. NOTE: 3dB stands for 3d Builder. Yes, the Microsoft 3d modeling app that came with Windows 10. :P
