Well, I got bored today and sat down with AutoCAD. I've been itching to make a shot maker for a while now.
Since the board software won't let me upload a .dwg file, I exported it as a PDF.
If you would like the actual drawing to play with, feel free to PM me.
*EDIT*
I forgot to include a dimension. A corrected drawing has been uploaded. I forgot to indicate that the holes for mounting the drippers were spaced 1.250" on centers.
