Tent Pole Connector with Captured Nut (M8)

thingiverse

This connector allows you to join a tent pole (with a J adapter) to your caravan, roof racks or other solid surface. Use screws or rivets to attach to the solid surface. Accepts M8 bolt with a captured M8 Nut. Nut will push-fit and should be snug. Can glue this in if you want to be extra sure. Use with a wingnut or my M8 bolt handle to be able to easily hand-tighten the bolt. May need to drill out the holes a bit to suit your fasteners of choice.
