I will try to get some get some close up pics of mine. I used 1x1 cut them to size of the window. I would cut your plexi about a half inch short all around so you don't have to drill thru your plexi. I dont care how careful i was i still broke mine. I made a sandwich with mine 1 1x1 then plexi then another 1x1 screw straight thru. just make sure you don't screw thru plexi as it will snap. They are a lil chunky but actually kinda cute.
Sorry not real good at giving directions. You can see some pics of mine at my byc page. I did mine quickly and with no help so they are kinda sloppy.
