Wall-mounted Mail / Filing Inbox

This is an updated model. The first model had larger hexagons on both sides of the back section. The hexagons didn't always print well.Improvements:all walls changed from 2mm to 3mm for a sturdier holderthis version changed to smaller hexagons and only put them on the frontwidth of back section increased to about 9 ½" (around 238mm)---- I wanted a small inbox to keep mail and paper that needs file off my desk. I also wanted to use the pattern feature of FreeCAD. This is a wall mounted holder for 8 ½" by 11" papers (a little of a tight fit), and mail.
