Speed Tank Side Covers

Does your Speed Tank fill up with sand or snow even with a cover on? Seal up the sides with these caps. Insert and glue the caps from the inside as shown. No supports are needed for the little overhang,

If I were printing from scratch, I've included the covers integrated into the side walls. Hmmm, do I hear remix? :-)
