Modular picture frame

Modular frame with different assembly possibilities. The pictures show a finished example and a screenshot of some possible connection methods. These are the available dimensions:9x14 (cm)10x15 (cm)13x18 (cm) 2x3 (inches) 88x54 (mm)Please note that different dimensions are not compatible. Soon there will be a new modular frame version that allows to assembly different frames dimensions. WARNING:Internal and external pins are different. Internal pins are slightly deeper than the externalI uploaded also a single pin to check the tolerances. It is very tight, but I think it's better to avoid a loose fit
