Do you have a duct that is located between the baseboards at floor level? We are able to make a geometric register with exact overall dimensions to fit your space. Then we can laminate around the edges to give you enough thickness to where the front is about flush with the baseboard. Or we can make it sloping, like a traditional gravity baseboard register. Cost is $1 per square inch of overall dimensions. For example, a unit that is 14 inches wide and 6 inches tall would be $84, regardless of whether it is sloping or non-sloping and regardless of thickness.
