I designed this because I am quite fond of attaching placards, front flaps, etc to plate carriers the way Ferro does it; using G hooks. Not all placards can come with G hooks and not everyone wants to break seams and sew in a g hook. This model allows you to adapt most placards to use g hook-style mounting. In the example photos I have a Haley Triple Rifle Mag Placard attached to a Spiritus LV119 and a Spiritus Microfight MKV attached to a Ferro FCPC. You will likely have to cut or otherwise uninstall the buckles which came installed on your placard.

I printed these in ASA with a .6mm nozzle and .28mm layer height.

Obviously this part is not and will never be as strong as the metal product it is attempting to emulate, but depending on the material and use case it should work just fine, considering the bulk of the placard weight is secured by velcro.
