Simple Keychain and 3D Printed Fixture or Jig

Information

      I created a custom fixture for my bamboo keychain project using CAD software, then brought it to life with my 3D printer. For anyone unfamiliar, a fixture (also called a jig) is essentially a guide that holds your workpiece in exactly the right position—it's a total game-changer for manufacturing because it ensures every piece comes out identical without having to measure and realign each time.

I use mine with my laser cutter, and it's made the whole process so much smoother! Instead of repositioning each bamboo piece manually, I just drop it into the fixture and let the laser do its thing. The best part? Once I had the fixture dialed in, I designed a bookmark outline that works with the same setup, so I can quickly switch between making keychains and bookmarks without any fuss. It's amazing how much time and effort a good jig can save!
