remix of Maglite "D" cell flashlight holder for Multiboard w/ Multiconnect

Remix adds:

• enlarged slot at front of holder to allow the Maglite to be inserted from that side of the barrel versus having to slide the barrel through from the top of the holder
• adds multiconnect connector to the back for very secure and easy connection to the multiboard grid (https://www.printables.com/model/716558-multiconnect-generic-connector-for-multiboard)

Special thanks to jfusco for the Multiboard version of this holder
