12x12 would be great. The Cameron base is only 4.11" wide x ~ 6.5" long. It has three holes through the base.
If possible, it needs a 1" diameter hole through the base to hold the dropper bottle of mineral oil. The Cameron has three oil “pots” that need a few drops of mineral oil every 12 hours of continuous run time. Keeping the oil convenient reduces the risk of using the wrong oil. The dropper bottle is currently attached to the Cameron.
I did not put oil in the oil pots since the Cam is lying on its side in the cabinet. As soon as we set it up we need to put mineral oil in the 3 pots.
If I remember I will bring a jar of bright Testor’s paint to paint the lids of the oil pots to make them easier to find.
