Another Screen Fame corner I couldn't find.
The square on this one is 3/4".
Since there wasn't enough left of the inside corners on the originals for me to tell, I went ahead and added the little guide for the screen rubber to make the inside corner. It worked fine for the one I worked on but if it doesn't work for yours just cut it off ;)
Depending on you printer's accuracy this one may be tight so a little filing or persuasion from a hammer to tap it in may be required ;)
