This tool can be used to easily level your drill press table perpendicular to the drill bit.

Print it with 0.2mm layers and insert 4 pieces of 8mm diameter, 3mm thick magnets. The magnets should be press fit, no glue needed. 

The holes on the back of the model can be used to press out the magnets, if you don't like the model.

I attached the model in Fusion360 and STEP format, so you can customize the parameters.
