Broadway Playbill Frame

This is a snap-fit 2-part frame designed for hanging theater playbills.  It is sized for NY Broadway playbills, taking into account small variations between the 9 I had on hand.  I'm not sure if this size is common internationally, but please share your results if others fit.  

The backplate is designed and tested to snap fit into the frame without any scale adjustments.  There are holes in the backplate designed to accept the linking clips if you want to hang several playbills at once.  This works in columns, rows, or a grid.  I am able to easily hang a 3x3 grid from a single nail.  There is a spacer clip that should be used to fill clip holes around the perimeter of a grid to keep the grid hanging flat on the wall.  The interference fit is designed to work in the default printed sizes.  

The design was tested using 3 perimeters and 0.2mm layer heights, infill percentage is not crucial, 10-15% is enough.  The provided 3mf files are my recommended printing orientation.  A brim may not be necessary for the frame, I will test printing without the brim on future prints.  

To assemble the frame first place the frame face down, and then place the playbill into the opening on the back.  Then press the backplate into place until it clicks in all 3 locations on each side.  There are 2 hanging points in the backplate, the upper triangle is ideal if the frame (or grid) is balanced.  The flat side of the lower triangle can be used to level the frame if it isn't balanced.  I used a kitchen scale to weigh each frame in order to build a balanced 3x3 grid.
