Post mount for battery maintainer

I keep 2 cars on batter maintainers and didn't like the messy cords all over the floor so I came up with this mount.  

Just print 2 of them to make both halves of the mount.  The holes for the hardware that joins them are for an M5 insert and screw while the holes to mount the charger are M4 (because that's what fit the mounting holes in my chargers).  The f3d has parameters for the dimensions of the post so you can modify easily.
