3D Printer Bed Leveller

Getting a 3D printer bed level is critical for producing decent printed objects. I found that the 4 screws of my FF Creator combined with a sheet of paper couldn't get me near to the accurate position I wanted, so I designed this object.

To use, start by leveling the build plate as near as possible using the mechanical raise/lower screws. Then run this print. If you are using Simplify3D then turn on the skirt option, as that helps. With Simplify3D you can also define to stop printing at a given height, and if you set this to the layer height of your bot then it will print just that one layer (which is all you are really interested in).

Set your print speed reasonably low. This gives you time to do manual adjustments to your build plate level in real time. Once you've got your build plate level you can experiment with the speed to find what speed is right for your bot and filament to print that first layer.

As the first layer goes down, manually micro-adjust the mechanical scre
