i have a fiber laser marking machine and i often times found myself needing to engrave in weird spots on items i couldnt lay flat so what i do is attach my work to a ball vice.
ball vices are really expensive so i figured out a way to make my own for 25 bucks using a few dollar store parts.
i made a video tutorial if anyone is interested .
video can be found on youtube by searching " DIY dollar store ball vice"
