I bought the cnc kitchen pinecil heat-set insert adapter and wanted to store it in the same box as my pinecil and 5 other adapter I had for it. Since I could only find boxes for 5 tips, I decided to design my own.

The design uses the excelent gridfinity-rebuilt-openscad project as its basis, so if you want, you should be able to adjust parameters to suit your own gridfinity system. I use the standard 6x2 magnets which should be snug fit, so you don't need any glue for this.
