FlashForge Creator Pro Z-Axis shim spacer

The original [Z-Axis shim spacer by DrLex](https://www.thingiverse.com/thing:1886458) doesn't fit into my Creator Pro. I think that there are small differences in the printers. If you made the same experience, feel free to try it with this one.

I made remixes with a spacer height of 1-5mm.

All my thanks to DrLex for the original design!
