Klaus Thoeni proposed the following answer:
Hi Justin,

the problem is the material in gridConnection and pfacet. If you use
this approach you should only use the material once, with the gridNode,
see below. The rest is set up based on that material.

box.append(O.bodies.append( gridNode([-boxDem[0],-boxDem[1],0],steel_r,wire=False,fixed=True,material='steel',color=color) ))
box.append(O.bodies.append( gridNode([boxDem[0],-boxDem[1],0],steel_r,wire=False,fixed=True,material='steel',color=color) ))
box.append(O.bodies.append( gridNode([boxDem[0],boxDem[1],0],steel_r,wire=False,fixed=True,material='steel',color=color) ))
box.append(O.bodies.append( gridNode([-boxDem[0],boxDem[1],0],steel_r,wire=False,fixed=True,material='steel',color=color) ))

O.bodies.append( gridConnection(box[0],box[1],steel_r,color=color) )
O.bodies.append( gridConnection(box[1],box[2],steel_r,color=color) )
O.bodies.append( gridConnection(box[2],box[0],steel_r,color=color) )
O.bodies.append( gridConnection(box[2],box[3],steel_r,color=color) )
O.bodies.append( gridConnection(box[3],box[0],steel_r,color=color,) )

O.bodies.append( pfacet(box[0],box[1],box[2],wire=False,color=color) )
O.bodies.append( pfacet(box[0],box[2],box[3],wire=False,color=color) )
