This is a very compact smartphone stand. You can put it on your key chain so you always have it when needed. To assemble you will need one 4-40 nut and a 4-40 1/4" long rounded head screw. Put the screw through the thumb nut and glue in place. Place nut in the groove of the top plate and assemble with the thumb nut. Glue the assembled thumb/top plate with bottom plate. The key chain hole sits above the bottom surface so it doesn't interfere with the stand. Adjust the position of the thumb nut to get your desired tilting angle. I tried with iphone 6. It works fine with most angles either landscape or portrait. Enjoy!
