This is a picture frame (around 60cm 80cm ) I did for stretching a canvas map of a LARP.
I designed it for a future insert in an IKEA Ribba frame.
It is 5 ⅛" birch plywood, glued and joined to make each sides. Needed 5 sheet for complete design, may be optimized for 4 but not less. Cut and assembled in 1 day.
I model it in Autodesk Inventor based on traditional framing.
Now I need a front mat and to restretch it, I didn’t do it properly the first time.
