8x10 Wet Plate Holder

Update March 10, 2020 - This design has now been replaced by a new version.

This is a printed wet plate holder for 8x10 plates. It will hold plates from true 8x10" down to about an eighth of an inch off each side. I've included the FreeCAD file, and you should be able to modify the design significantly just by changing the values in the Dimensions spreadsheet.
