Model Description: The Open M3 Nut Driver is a modified version of the standard M3 nut tool.

Purpose: This model is designed for easy and efficient tightening and loosening of M3 nuts.

Construction Features: The driver features one opened side for better nut handling and a hollowed main section, allowing for the use of taller and auto-lock nuts.

Printing Recommendations: It is recommended to use a print resolution of 0.2 mm, but a 0.1 mm setting may provide a better fit for the nuts. Printing in PLA is suggested.
