This 3D model offers an efficient solution for the base of Loop Earplugs, combining a practical design with optimized printability for TPU. Every detail has been carefully considered to ensure a clean and soft result.

Its dimensions and proportions are precisely engineered to fit silicone ear tips securely while allowing for easy assembly and removal. The balance between a firm grip and user convenience is a key aspect of the design.

From a printing perspective, the model is designed to be produced with minimal effort and minimal material usage, eliminating the need for supports.

Another highlight is its soft and ergonomic shape, which integrates into the earplug setup, providing lasting comfort even during extended use.

This model was designed with the aim of combining comfort, practical usability and ease of printing, and it's the best choice for those looking to replace or customize their earplug base.
You can try to reduce the infill to 10% if you like a softer result.

You can also print it with PLA, but I suggest you to keep the layer height at 0.08 mm: the result will be the same, but it could be less comfortable for a prolonged use.
