I was tired of trying to hold the mast of my US12 RC model sailboat as I attached it to the hull…I needed a third hand. This “third hand” snaps to the hull and the mast, allowing you to connect the shrouds, fore and aft stays. There are two versions: one for new aluminum masts, which are approximately ½" in diameter, and one for traditional wooden masts, which are approximately 3/8" thick.
I printed these out with a 15% fill using PLA, and they work great.
The author marked this model as their own original creation.
