Strong adjustable lifter

Strong model 50% stronger than single thread models.

Recommended 4 perimeters and minimum filling of 40%, the double thread gives an extra support of 50% over the normal thread, allowing to achieve high weight loads.

Models version V0 = thread pitch 3 mm M60X3 M30X3 (Strong scalable X1 Y1 Z1 )
Models version V1 = thread pitch 4 mm M64X4 M36X4 (larger pitch allows scaling in X1 Y1 Z 1.5 times while maintaining a good thread)

Enjoy
