PT17 "Stearman" model plan connectors

I made these for my neighbor's PT17 model plane. His brackets broke and they were not being made anymore. They are made to stick right into the foam and be glued in. There are two different types of connectors that I designed but he used all of the second version in his plane. I printed them with a .25 nozzle as it had some very small features that would look rough with a .4 nozzle. STEP and SLDPRT files included
