[P6 - LedMatrix] Panels lock brackets

I'm using these brackets to hold my four 32x32 LED Matrix Panels.

I'm using as a base the one from TheLastGMan.
He only shared a bracket to hold them horizontally.

I created 2 others to hold the panels Vertically.
One model is used for the side brackets with the little pin.
The other model is used in the middle without pin

EDIT1: I'm adding a square bracket to lock the 4 panels in the center
