The pull handle operates a single door, and the secondary door can only be opened when the main door is open. The parts can be used on both right and left doors. After printed, you can flip the design to orient it correctly for your desired door configuration. 

The reason I created this model is the plexiglass panels were about 5mm too long and I had issues both closing them and using the original door astragal. 
My design works when there is a pretty noticeable gap, like the one I left after I cut roughly 6mm from both of the panels.
I also found that two pull handles are too many, because I always end up opening both the doors. It's an angular enclosure after all.
