Overview
Tired of your expensive helmet rolling around the table or getting scratched by hard surfaces? The Helmet Donut is a simple, essential accessory for every rider. Designed specifically to be printed in TPU, this stand provides a soft, "grippy" cushion that stabilizes your helmet while protecting the finish and the bottom trim.
Whether you're installing a comms system, cleaning your visor, or just looking for a dedicated spot to store your lid, this donut has you covered.
Key Features
- TPU Grip: Unlike plastic stands, the TPU construction ensures the stand stays put on your workbench and your helmet stays put on the stand.
- Protection First: The soft material won't mar your helmet's paint or damage the delicate bottom rubber seals.
- Stable Geometry: The wide base and contoured ring are designed to support everything from lightweight carbon racing lids to heavy modular helmets.
- Ventilation: The open-center design allows for airflow into the bottom of the helmet, helping to dry out liners after a long ride.
Recommended Print Settings
While this is a straightforward print, here are the settings I used for the best balance of squish and support:
- Material: TPU (95A or 98A recommended)
- Wall Loops: 3-4 (to provide structure for the outer rim)
- Infill: 10% – 15% (Gyroid is best for consistent "squish" in TPU)
- Top/Bottom Layers: 4 layers for a smooth finish
- Supports: None required! The geometry is designed to print cleanly without them.
