Building nuc boxes

I finished assembling 25 nuc boxes this afternoon as I've expanded my nuc production this year (and almost sold out even so). Now for the boring part - painting.  These boxes last years; the old box in the top left is 3 years old (with a mismatched lid) and has no serious issues.  I use exterior grade plywood (not pressure treated), with prime and paint.  The red painted line is actually a sideways letter I.  To keep track of the nucs and also to create a unique front to assist with orientation flights  I cycle through the alphabet painted on using a template. If like to build some of these yourself, I have the cut template in the Build it yourself area.
