Ender 5 Plus bed mounting shim

I had an issue with my Ender 5 Plus in that the front was lower than the back when everything was equal. This resulted in the rear adjustments being much tighter than the front and became an issue when I switched to solid silicon mounts.
I made this shim to insert between the bed gantry and the z gantries on the lower side. Just scale the z axis to the thickness needed. Since there will be no heat applied to these shims any material will be fine.
The bed level was just a quick tune after installing the shims (and solid silicon mounts) showing a nicely level bed (looks worse than it is, check the scale).
