The rounded bevel for large or scaled-up Maker Pen objects has been acknowledged as not working very well (esp w/r/t the hitboxes). I think the perfect "happy medium" between sharp edges and rounded bevel (i.e. Rec Room style) would be a toggle slider like this:

. . |--------------|--------------|

Round ---- Sharp Bevel ---- Square

That way, you can select rounded (Rec Room default), sharp bevel (maintains Rec Room style but without the awkward hitboxing and texture stretch associated with the round bevel scaled up), and square (no bevel).
