75mm head and a pin you should print at leat 82 of (I printed 100, broke 3). I suggest hollowing it out too or use the file I printed (with hollow in file name). There is a special place in hell for you who glue all these pins in place... I dipped in resin and held each for 10 seconds while shining a uv light. It was very simple and WAY easier than glue. Just use sparingly and it REALLY helps to print in clear or light resins.
As for the nails, I could include them all in place in the file.... but where's the fun in that? Also makes it easier to paint.
