Mounting a 4in lazy suzan bracket on a board i use for spray painting. The board has holes for three pegs, and will mount over center hole. I left the v1 cap so i could have access to the whole, or use these pyramid stands I use.
I used a 4" lazy susan bracket by Shepherd hardware products (they are the ones Menards sells).
v1 - basic , has hole in middle
v2b - basic, added some prongs for easier turning
v3 - with pyramids, hopefully these will keep bottom elevated and prevent pain adhereing it to the base, or weird streaks. (haven't printed this version, the original was a tight so i add some slack in the recess)
