Seeing the popularity of an EDC Altoids tin, I created 2. One of these has a smattering of items while the other is a small ratchet with bits. I hated how both these tins would float around my bag. In response, I created what I am calling the EDC workbench. This allows you to keep 2 tins together and have an area to keep removed bits and pieces in one place.  There are 2 versions of the workbench. One that is numbered and segregated into 4 sections and one that provides the most area for parts. All versions are designed with a ramp on each section to allow easy removal of small parts. The numbered version also has large “+” marks on the bottom to allow for easy centering of stick on, anti-slip rubber feet, should you want to add those. Tins are held in by a nub in each section in addition to their tight fit. This nub allows a nice “snap” when the tin is pushed all the way into the workbench. This tight fit and nub will remove the paint from areas on the tin. I have modeled this specifically for American 1.76 OZ (50g) tins. Apparently there are some overseas Altoids tins that have different dimensions, YMMV. This will most likely NOT work with the brand-less, unpainted tins on Amazon either. If your printer does not create dimensionally accurate parts, you may want to scale the workbench up a few percent to ensure that the tins will fit. The first 10-15 loading and unloading of the tins will be difficult as the nub and any high points wear down. There are 2 holes in the back of each section that you can use to push the tins out should they get stuck or to assist with the break-in process.
