This is a remake of alaubham 'Tap / Die Tray for 12 Piece Irwin Hansen Metric Set'. I added the small slots to make access to the parts and added a cover case. The cover was printed in PLA and the tray with PETG because that is what I had. I do not think the material makes any difference.

The 2.25" x 4.25" data-sheet is handy. I give the drill size for the metric taps. I got the information from engineering tables and rounded them. Most of us do not have the actual drills suggested so I picked something close but even the 'close' will not be something you have - just do the best you can without over boring the hole.

5-10-2021 As a request, I have made a metric and SAE cases. I have never printed these objects. They should be printed as shown.
