I chose to continue with my current setup until I get the time and motivation to upgrade.

I will build a new server from scratch. For that, I bought an used mainboard for a few bucks, which has 6 SATA slots.

Instead of using a caliper, like the others have said, you can measure the distance with your printer if you don’t have such a tool.

Just go into the “Move axis”-mode, and move your nozzle from the home position to the top layer.

Let’s say your coordinates are now X0, Y0 and Z49,3.

You can then move the object in your slicer by just changing your Z axis to -49,3.

Just make sure you:

1. Get a good first layer, without getting an elephant’s foot.
2. Don’t use too much glue. A good choice is acrylic glue, but it will alter the surface if it droops out or is too far outside.
3. Don’t mechanically stress the object too much. It won’t be as strong as before.
