Soldering clamp

If you've ever done any soldering, you know how invaluable an extra set of hands can be. Here's another clamp creation designed to make your soldering tasks easier. To complete this build, you'll need either two neodymium magnets (Ø10 mm x 10 mm) or a suitable spring—though you'll need to research the ideal spring specifications yourself.

Any filament type works, but one with high temperature tolerance/resistance is better.
