Handlebar Extensions: 3D Models and STL Files
This collection gathers STL files for handlebar extensions, risers and accessory mounts. It covers bicycles, mountain bikes, trikes and scooters, so you can find a shape that fits your bar diameter and mounting point. The models are meant for 3D printing and often include several parts. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.
How this collection is put together
Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

«Handlebar Extensions: 3D Models and STL Files»
Handlebar extensions range from simple plugs that add a second bar to full risers that change the grip position. Some are designed for standard bicycles, while others target mountain bikes, trikes or scooter handlebars. Accessory mounts are a separate group: they clamp to the bar and hold lights, cameras or phones. Adapter plates and plug-in fittings connect different bar systems.
Before printing, check the model page for the intended bar diameter, the number of parts and whether assembly is required. Look at the author's photos of real prints to see how the extension sits on a handlebar. The material and settings the author lists matter, especially for parts that clamp or carry weight. If supports are needed, plan for post-processing.
To narrow results, try synonyms such as bar extender, handlebar riser, bar adapter or accessory mount. Related topics include bike computer mounts, light brackets, phone holders and trike fittings. You can also search by the type of vehicle, for example bicycle, MTB, scooter or cart. Combining a part name with a mounting style often brings up different designs.
