Solder board holder

A solder holder for boards, the one I had was too high and I couldn't use my Amscope (microscope) so with this one the board stays low enough. Uses the 8mm rods from my older 3d printer and I still have to cut them with a smaller size.
Parts:
4 - M3 x 18 screws
4 - M3 nuts (heat up the nuts with the solder iron and insert them, mine was too tight and may break)
2 - 8mm rods - (the size you want)
