Prusa i3 3D Printer Anti Backlash v2.0

After using a part designed by Tech2C I have modified it to have a locking screw. This allows the X axis to be locked onto the top Z axis nut. If you've ever had issues where the X axis does not sit on the Z axis nut correctly, this will solve it.

For each M5 Z lead screw, you will need,

2 x M5 hex nuts
1 x spring with a 5mm bore
1 x M3 hex nut
1 x M3 bolt (I used an M3 x 10mm socket cap head)
