Zippo BitKit insert

This bitkit insert fits classic zippo cases.

Basically added a magnetic closure. The main body takes a stack of 8x3 magnets. You should be able to fit five in the stack (so you can customize the strength of pull), and a small piece of masking tape for a press fit depending on your machine's tolerance. Take a short screw into the small block and shove it into the lid where the cam normally goes, again wrap a little tape around it, if needed. Adjust screw until it just clears the main insert. The case should close with a nice snap and stay closed if you shake it gently. I stuck a small bit of foam in the lid over the bits to keep them from rattling.

The holes in the bottom are for rescuing stuck bits or popping the magnets out. A bent paperclip works fine for this. Once you get everything fitting nicely it shouldn't be an issue. The smaller pockets around the top were originally for 2mm disk magnets to help with bit retention, but I ended up not needing them, personally.

I would not recommend carrying this loose in your pocket. Best to use a belt pouch or something. But so far I've had no problems with it. I printed mine in PLA+
