Gridfinity 1x1 Threaded insert soldering iron tip holder

I made this to hold my threaded insert tip set. It's stackable when filled, and the bits are arranged in size order (I've given a bit more space for the larger bits). They are arranged clockwise in increasing size from the bottom right. The M2 bit is a bit fiddly to remove with large fingers like mine, but tweasers etc quickly solve that problem, and the rest are easy to remove. I've left a little bit of play for the threads - so they don't get sticky in the sockets. The holder should be easy enough to remove - it's a fairly tight fit in the 1x1 gridfinity cell, but I've left room for a nail or set of tweasers on one side - and I find it fine to get to. 

The threaded insert set I designed this for can be obtained from Amazon here: https://amzn.to/3BFAJas, and these are the magnets I use for all my gridfinity stuff: https://amzn.to/3DFTKtO.  (Note: These are associate links, which means that they don't cost you any more, but I get a small cut if you purchase via these links. This isn't a big money-spinner, but I find it so useful to have sub-components linked in models that I download - so I know I'm getting exactly the right bits without much research, and it helps justify my tinkering!). 

I hope you enjoy this model. 

Kudos again to @scheff for the blank bins, and obviously Zack Freedman for the gridfinity movement..
