105mm M1060C Hex Grill

Just a slight mod of Shroomalistic's M1060C Hex Grill.
I found that the exterior diameter was 104mm and after printing and installing the grill it was slightly undersized inside the cups.
I added an extra 1mm to the outside diameter of the ring and now it fits perfectly inside the cup.

It should probably be noted that neither of these designs sit flush with cup lip due to the bosses used. They stand outward from the cups.
I actually prefer this design because it helps protect the paint a little.
