Description:
This 3D printable model is a robust and ergonomically designed handle for a lawn mower pull-start mechanism. The handle features a basic rectangular grip to ensure comfort during use and a sturdy structure to withstand repeated pulling forces. The design includes a hole for attaching the pull cord securely. It is an essential replacement part for maintaining the functionality of lawn mowers. did not add any round edges so that you can print this fast using turbo mode.

Notes:
For all printers, increasing the infill density ensures the handle is strong enough to endure repeated use.
Use slicer software to preview and adjust support settings to achieve optimal printing results without compromising the model’s structural integrity.
Post-processing, such as light sanding, may be required to smooth out any rough edges or remove support remnants.
