Tubular housing designed for an electronic speed controller (ESC) of a 1:10 scale drift car. The author uses PETG and clarifies that the piece shown in their photograph has been polished. They do not identify the specific ESC model nor do they provide information regarding universal compatibility, a degree of waterproofing, or a cooling function.

Preparation, compatibility, and printing

Compare the internal dimensions with your ESC and reserve space for connectors and cables. Also, check that the housing does not obstruct the necessary ventilation for the equipment. Polishing is a post-processing finish, not an automatic property of the print. The source does not specify layer height, infill, or orientation; prepare a fit test before installing the electronics.
