SIO Plug for 400/800/XL/XE Atari 8-Bit Computers, PLA Sized

cults3d

I was fed up not being able to get reliable sized SIO plugs when I needed them. norm8332's was sized to print with ABS, piep3d's was sized just a little too small making the plug loose in genuine sockets and the crimps hard to get into the holes. I went back to the original SIO specs, got the mechanical drawings for the SIO socket and resized the plug down to 1mm less than the size of the socket. Crimps fit the new model perfectly and the plug fits original sockets easily but with barely any slack. I copied piep3d's idea and closed up the nut hole on the bottom of the shell, making it fit an m3 screw, 10mm or 12mm will do, cap, pan or dome head will work.
