A strong small clip for carrying and storing tripods and other devices with camera thread (1/4 - 20 or 3/8 - 16) I have tested it to hold 10kg where after the metal ring broke. The clip all so works well as a string pod. Just add a thread rod, cut a bolt to size or buy a 1/4 to 1/4 Adapter and tie a line through the ring and you are done.There are three models: Print the selected model with 100% fill or at least with wall thickness enough to handle the thread insert / converter Then used screw in the thread with no glue needed, it can however be added for even stronger connection. If you want to test if your printer is able to print the thread correctly then you can start with this thread repair test: http://www.thingiverse.com/thing:646221
