This is a level for pinball machine playfield. This is meant to be placed between the flippers to get a more accurate level. This supports be front to back and side to side leveling.

v1.1 Did some minor cleanup and rotated the model to sit level on the print bed.

The mounts are for Bubble Levels measuring 18x15x52mm.

Here is a link for the levels I used on Amazon: https://www.amazon.com/dp/B0C3HS4HQ9

Note: The item description mentions that they are 15x15mm, however I measured them as 18x15mm.

-- This is printed on its bottom with no supports.
