I've got this crimpingtool from aliexpress (i'm sure it's also available from amazon etc.), It comes with 6 different crimping dies and an allen key to replace the dies. It is often called SN-58B (which is just the designation of one of the dies)
Not liking how that just rolls around in the drawer and needing to practice with freecad I came up with this box.
Also I made this cheat sheet as I keept having to search which die to use for which connector.
Attention: The dies apear to not all having the same dimensions. I had to file away a bit on one of them so it fits its space.
