Ender3X bed leveling adapter

thingiverse

The Ender3X comes with two printing surfaces: standard and glass. When you want to use the other one, you'll need to re-calibrate the bed height because the glass surface is 2.2mm thicker now. Here's a shim plate that lets you quickly switch between them. To adjust the bed height with the standard surface, start there. Then, when you're ready to use the glass bed, simply place the shim on top of the Z-microswitch. The difference in thickness between the two surfaces is equivalent to a SDCard. Sand down the longer (top) section of the shim until it's even with the SDCard and you'll be all set. Before moving forward, make sure the adapter allows for free movement of the microswitch.
