About this 3D model

Created a larger retractable to hold a 3mm z probe (1/8 inch brass rod I purchased at Lowes. Moved the probe so it is on the outer edge of the Effector. Made the retractable a little taller also to support the larger probe. All in all the probe is now a lot more sturdy that the original allen wrench version and I can make the probe any length I want!
