I created these drill and tap holders to work with my Slim Packout Bins for Milwaukee bit holders, but they also work in the original Milwaukee bit cases.
Die Holder for Milwaukee Packout bins
I am only including an STL for the Dewalt DWA1450 Metric tap, drill, and die set. Tap diameters vary considerably among manufacturers so you'll have to customize your own.
The customizer is pretty complex.
1) Ignore the dummy parameter, that just is there because for some reason customizer ignores the first variable.
2) Choose if you want to have labels
3) Choose how many "sets" of taps and drills you want
4) Measure and enter the shaft diameter of each tap and drill (and labels if you so choose).
5) Set the min_spacing so that the taps and drills are evenly spaced.
6) If the bits and taps are too tight, either adjust each individual one, or adjust the global "fudge" factor.
7) Ignore the holder and case connector parameters unless you need to adjust the size of the holder or the fit of the connector.
8) If you use labels you can adjust the font, font size, and indent of the labels. You can also use spaces before the labels to align them properly.
Print the holder on it's side with the text facing up like I orient it in the files. Support is required touching the base plate, otherwise the springs won't print correctly. If you have a well tuned printer you shouldn't need supports for the individual tap and drill holes.
I don't have the files set up to automatically change colors. You can either print the labels in the same color and them paint them, or switch filament on the 56th layer if you keep the default body depth.
