A remix of cibermae's picatinny rail version on Thingiverse.

• Adapted to arca rail
• Added hole in arca section that can be tapped ¼-20 for a friction screw if desired. I don't find it necessary
• Rail is spaced to clear external weights on an MDT chassis
• Cut off the tabs holding the display in. The model prints easier and the display is easily retained when it has a wrap of electrical tape around the seam of it.
