SMD Component Tape Magazine mods from Lord Asdi
Minor mod of SMT cartridges designed by Lord Asdi (so-called) at: https://www.printables.com/@LordAsdi_1250566
Essentially I sucked the STL into Blender and the model is tidy enough I was able to widen the exit of the cover tape slot (in the top), so as to avoid the tape having to be pulled through a 90 degree bend. Whether that's a problem or not, ... , dunno.
I'm just killing time while printing the original.
I'll update and add 12mm and 16mm variants as I experiment, but surely you can pull the STL into blender your own self! Go on! Try it, it ain't that scary.
