Wire coat hanger twisted into a U shape to fit into plastic tubes from a hobby shop. The ends of the U have notches cut by a Dremel. Two pulling springs hooked into the coat hanger pull it down into the plastic tubes. The plastic tubes are epoxied to a plastic base, which is in turn epoxied to a cheap toy weaver scope mount. Foam tape top and bottom cushions the grip.
I got the idea from a cell camera tripod I saw on Facebook's Wish. Next time I'll just buy the cell camera mount and cut an old scope ring for the base.
