The file 'Printable Tattoo Inkcap 3D Printer Model' is (stl) file type, size is 5.3KB.
Just did this to see if i could get close to my favourite ink cap by guessing. Low and behold it is nearly spot on. Use this at your own risk, I take no responsibility. However food grade PLA and if you were to use it immediately after printing it should be nearly sterile ( normal ink caps are not ) and are not made of PLA which in time could bio-degrade.
This was just and experiment in finding a useful thing to make. enjoy and use it as you will.
