Display easel

Dear wife wanted an easel to display a plate she liked. I didn't want to buy hinges, so I borrowed a printables design from this page:

He posted a FreeCAD model and I use FreeCAD, so I uploaded his model and modified it for my purposes.

The M4 bolt is from the FreeCAD fasteners workbench. I haven't had much luck printing threaded holes, so the print I'm uploading has holes suitable for an M4 tap to make the threads. The tap is pretty cheap on Amazon.
