Flashforge AD5M toolbox

I'm making things for a new Flashforge Adventurer 5M. This toolbox hangs on the frame. It's a snug fit but there are two screw holes that line up, if you want to fasten it.

Test file. Being unfamiliar with the printer I did a test file to see if I like the way it fit. Also, the extruder gets real close to the frame, and I wanted to make sure there was space enough..

Extended version. It's longer. Doesn't hang. It has to be attached with nuts / bolts.
