Cuisinart Food Processor Adapter - DLC8 motor/base to DLC7 blade/bowl

A friend had a miss-matched Cuisinart Food Processor with an older blade/bowl (DLC7) and a newer motor/base (DLC8). I made a simple adapter to make them work together. The Venn diagram that has "People with 3D Printer" and "People with Miss-Matched Food Processors" may only include a handful of people but oh well!
