Cữ kê hỗ trợ hàn header pin cho Breadboard và PCB

If you've ever soldered header pins to a board, you know it's a pain to get them straight. 

You can stick the board and pins into a breadboard while soldering - that usually works. But if your board only has pins on one side, the other end just sits there wobbling around.

That's why I made this little spacer. It plugs onto the breadboard and holds up the empty side of the board while you solder. Simple, but it gets the job done.

I printed mine with Prusament PLA at 0.2mm layer height.
