T-Rex 450L Dominator Battery Plate

100% infill. Be careful at the top, this may get too hot and smudge. Options to handle this are slower printing, more copies at a time and reducing nozzle temperature. Not as stiff as the original carbon so the loop fastener has to cover both cut out where the strips to fasten the battery go around. That way the deflection is minimized and it smoothly slides in.
