This is a customizable handle for a wheelbarrow. It was designed for rod with a diameter of 30 mm. It may as well work as a handle for other uses. If needed, there is attached an .f3d file, where you can customize it to the desired rod diameter.

Avoid crossing perimeters (combing) should be enabled to prevent unwanted stringing inside. Print it as it is - on the unclosed side.
For this kind of application, printing with ASA or similar filament is recommended.
