I wanted to make a small portable phone stand that was always on hand. This is a print in place file, no support required. Set your printer to at least 50% infill and pattern side up. There will be a slight fusion of all moving parts after printing. Insert a small flat head screw driver in the opening at the end opposite the keychain loop. Give a gentle twist to free up the fused swing arms. Once a small opening has be started work the screw driver down 2 thirds the length of both arms, “Be gentle”. Once open, work the parts back and forth a few times to loosen them up. Note there is a small gear mechanism built in, so work both arms back and forth TOGETHER.  When finished close the swing out arms in, close the top with a satisfying click, attach to your house or car keys and enjoy at your leisure. ;)
