Wet Plate Wall Hanger

This is a simple hanger for mounting an ambrotype or tintype to a wall.  The model itself is fully parametric so you can easily adapt it to any size using the included FCStd file, but I've provided a variety of pre-sized STL files as well.

To use this, first pick your size.  The STLs come in a top and a bottom half, and they're named according to the pattern (tin|ambro)_width_design_(top|bottom).stl.  For instance, the file ambro_120_chevron_bottom is the bottom half of the chevron design, 120mm wide and sized to fit an ambrotype (glass plate).

Each STL file includes a pair of holes that should snugly fit a ¼" dowel (or a 6mm dowel with a little looser fit).  You can accommodate any size plate by cutting a length of dowel to the appropriate size.  ¼" dowel is thin enough that you can easily cut it with a hand saw or even snap it into parts.  The fit doesn't need to be exact, just close enough to get a centimeter or so of the dowel into the holes on both sides.

To assemble just put a bit of super glue or epoxy into the holes or on the ends of the dowels, then insert the dowels into the top and bottom.  You can slide a plate into the slot to serve as a sizing aid, just leave a millimeter or two of extra space so it will be easy to insert and remove the plates once the adhesive dries.  Then you can hang the plate on a nail head using the sawtooth hanger built in to the top half of the hanger.

There are four designs included here:

• Plain: Simple, rectangular hangers
• Chamfered: Rectangular design with a chamfer on the front edges
• Filleted: Design with rounded front and edges on the visible portion of the hanger
• Chevron: Similar to the chamfered design, but with outer edges that slope slightly inward towards the plate
