I’ve never seen a factory one, but I have made one in the past. It is very easy to do. Take a plano 3701 and with a dremel tool or a very sharp knife and sand paper cut out all of the inserts. Then head to a craft store like hobby lobby and buy some closed-cell craft foam. 1/2″ will be perfect. Glue it to the bottom of the box and you have a great big spoon box.
Any of the plano boxes will work, but the 3701 is a slim design. 3701 is 14 x 9-1/8 x 1-3/8 inches
