HyperCube Adjustable Z Endstop by TechGirl_Mods

I have been asked to explain how the parts fit together.
If you look at the first picture above you will see how the red and blue parts are fitted.
The endstop micro switch is mounted on the endstop mount as shown in the second picture. The M3 nut is inserted in the slot in the back of the endstop mount.
Before fitting the endstop mount insert the M3x70 screw into the Adjustable mount V2 and fit the spring to the screw. Fit the endstop to the Adjustable mount and adjust the height with the M3x70 screw. Attach the assembled parts to the frame with an M5x10 and an M5 drop in hammer nut as shown in the second picture.
The trigger is bolted to the back bed rail with the remaining M5x10 and M5 drop in hammer nut and aligned to trigger the micro-swich as shown in the second picture.

After using the end stop since August I found that the end stop trigger was not sturdy enough and as I started off a print it finally the upright trigger broke off the base and I had to power off my printer to prevent damage to my hotend and bed.
So I came up with the latest design which strengthens the join between the upright and the base.

Change to the picture showing the correct orientation for the limit switch mount when in use.
I was getting annoyed having to drop the bed every time I needed to make a minor adjustment to the Z height, so I came up with this design. The design moves the adjustment from the bed to the frame of the printer.
The endstop switch and fixings from the existing limit switch are re-used in my design.
The endstop trigger bolts onto the extrusion that has the lead screw mounting.
Now I can make those small minor adjustments without having to lower the bed.
Additional parts required:
2 x M5 x 10mm bolt
2 x Tslot M5 hammer nut
1 x M3 x 70mm fully threaded bolt
1 x M3 nut
1 x long compression spring or 2 x bed levelling springs, fitted to the 70mm bolt for
tensioning the limit switch
I had problems sourcing a 70mm fully treaded bolt so I purchased an ordinary bolt and threaded it myself.
