The file 'Toothpaste Cap – Colgate 3D Printer Model' is (scad,stl) file type, size is 58.8KB.
I couldn't get other toothpaste caps to actually fit my toothpaste tube.
So I found this library and fiddled with the settings to produce this simple toothpaste cap that is easy to print.
it uses:
buttress_thread(16.3, pitch=2.1, length=8, internal=true,n_starts=1);
16.3 is the outer (largest) diameter of the thread (measured and then tweaked)
pitch=2.1 is how many mm there are between peaks on the threads (measured)
length=8 is how many mm long the threads should be.
I am not sure what internal and n_starts does.
The threads.scad and helix.scad I did not modify (except commenting out the demo)
