Gridfinity 5x3 quad dial indicator holder

Created to hold 4 dial indicators in a more compact layout in Zack Freedman's Gridfinity system. Each pair has a slightly different offset to suit the indicators I have: 2x Mitutoyo 0.0001", one Federal 0.0001" and one Chinese 0.001". Should work with most dial indicators up to 1" travel. Large back pockets so you can leave the mounting post attached to the indicator.
