CG Scale

This is a heavily modified and improved version of the original CG Scale project by olkal. 

Key Modifications & Improvements:

• Heat-Set Inserts: Replaced those annoying bottom-entry screws with standard M3 heat inserts (M3×5×4 mm). Assembly is now much cleaner and you don't have to keep flipping the frame over during the build.

• Dedicated Tare/Zero Button: Added a cutout and mounting spot (in Frame part) for a dedicated zero button on the housing for easy recalibration during power on. .

• Sturdy LCD Mount: It mounts directly to the main base for a sturdy, integrated feel without wobble.
