Self-sealing Stem Bolt

The best self-sealing stem bolt in the sector. A perfect gift for that engineer or handyman in the family. So many uses. Build yours today!
You will need to purchase two 50mm length, 13mm diameter, .8mm wire size springs. You will also need to buy one 10mm length, 6mm diameter, .5mm wire size spring. I recommend getting a bunch of springs, because more springs means stem bolts and more stem bolts means more profit! Here is what I bought and used for mine:

You will need to print one case, one base, one button, two plungers and two blocks. For print settings, you'll need to run supports on both the plungers and on the button. Everything else should print fine without supports. If you put a thick layer of paint on it or if your print quality is really low, just check to make sure the button and plungers slide in and out smoothly. If they catch at all, just sand down the holes a little bit. Here is a video to help with assembly:
