I simply used PLA to print (although ABS might be better due to its slightly more flexible less brittle nature). But the PLA print has worked great i can slide the dongle out of each holder spot and click them back in (the click is very satisfying in my opinion). I like to call it the "Tactical Dongle Holder" for fun but it has come in handy as anyone with an iphone 7 or more knows these dongle are never there when you need them and i seem to loose mine often. This is my fourth one. I have had this dongle longer than any of the previous ones. I made this model in Autodesk Inventor Pro but when i saved the file and loaded it into Cura it was wayyyyy too small. I do not know if this is a problem with Autodesk or Cura but you may need to scale the model up by 10 times when you load it. Hopefully this helps and comes in handy!
