I3 Z Limit Chock Block

"One less thing - That's good" - My favorite Forrest Gump quote!

This block can be used to lock-in your Z-limit switch height. This eliminates a critical variable which is the second most likely cause of needing frequent bed re-leveling. (read on for the primary cause and solution).

The block is a 10 sided irregular polyhedron, with the unique property that the opposing faces are each a different dimension. In this case, the five opposing sets of faces provide spacing of 22, 23, 24, 25 and 26 mm. Just turn the block to the size closest to what you need, and slide it under the Z limit switch. Then re-tighten while pressing the switch against the block. Use the bed screws to fine tune the level.

If you need different sizes, just scale this in your slicer before printing.

So what is the actual **primary cause of frequently needing to re-level the bed**?
The cause is: **Loss of Z rod synchronization**. This happens when one of the Z rods turns when the other does not.
