I needed to cover an ugly seam in an out-of-the-way place do I designed this 2.5" square keeper plate.
I used PLA with ironing turned on.
The holes are for M3.5 flat head screws. #6 will work too.
NOTE: The “texture” is Fusion 360 rendered only, does not show up in the model.
The author marked this model as their own original creation.
