This is a 3D-printable replacement for the upper part of the transducer mounting bracket for the ONVA KP-27F marine fishfinder/GPS.

The original upper bracket is prone to snapping under stress. This model replaces only the broken upper component (the gray part shown in the photos) and is designed to integrate perfectly with the original black base and the original toothed locking mechanism.

Printing Recommendations:

Material: PETG, ASA, or ABS are highly recommended for their UV and temperature resistance, which is crucial for marine and outdoor equipment.

Infill & Walls: Use high infill and extra perimeters (4-5 walls) to ensure maximum structural strength, especially around the gear teeth and mounting slots.

Note: The photos show the 3D printed gray part attached to the original black base for demonstration purposes. This download only includes the STL file for the upper bracket.
