Ballistic Shield Window

2 part window frame for a ballistic shield base on a Russian design, slightly different measurements though.

design is spilt into front and rear frames, rear is longer to have a sheet of acrylic or such glued onto and then slides from the back through the front panel and is either glued or screwed into place. both frames needed to be split in half in order to fit my print bed (220 x220) and then glued together.
