This is a reliable, fully functional 3D printable butterfly latch designed for panels, enclosures, and custom DIY projects. The design is mechanically robust, easy to assemble, and optimized for 3D printing. It is engineered to work seamlessly with a standard M5 nut.

Included STL Files (5 Parts):

Base: The main housing that mounts to the panel.

Spacer: Adjusts the tolerance and gap for a secure fit.

Core: The internal rotating mechanism.

Latch: The locking arm (cam) that secures the panel in place.

Butterfly Knob: The ergonomic handle for easy opening and closing.

Hardware Required:

1x Standard M5 Nut (and a matching M5 bolt/screw, depending on your panel thickness).

Printing Guidelines:

Material: PETG, ABS, or high-strength PLA for better mechanical resistance.Infill: 40% to 100% recommended for the moving parts and the latch arm to ensure durability.Supports: Designed to require minimal to no supports if oriented correctly on the build plate.
