I made this simple adjustable stand for model kits. Each arm can be adjusted by tightening or loosening the M3x8 flat head screw at the bottom. You need to print 4 arms and 4 nuts. I used M3 heated inserts like the ones in the photo, but you can also try using a larger screw and avoid using the inserts. Print the base so that the guide groove is at the top to avoid using supports.
