This is a simple STL to integrate in your 3D models like a project box or a control panel.
It's a model of a keystone bracket to accomodate standard keystone modules like ethernet or audio jacks.
Just make a 28 x 17.9 mm rectangle hole in your model and align the STL to the hole and the face to the face of your model.
It's super simple and super useful.
PS> Juste realized there are ton of this already... hehe... here's one more... :-)
