Added and printed low profile and low profile with a cup (not print the one with cup).

I was given a screw driver for work that I kept in my back pack in case I needed it (printer/copier/scanner networking, computer tech). It is a nice long shank magnetic screw with 6or so bits in the handle. Unfortunately the cap would constantly un-screw in my back pack and all the bits would fall out. I only needed the PH2 in any case. Overtime I went with a nice ryobi 4v, then eventually to a really nice dewalt gyroscopic electric screwdriver. I still use this one, the other downside it was always in the back pack and would over time poke holes in the back pack. I just happened to need this a few days ago and thought why not. So I designed this up. Took 3 prints for me to get it right, went 18mm threads, then 20, then settled one SAE 3/4-16 UNF. I may change the design to be a lower profile and maybe more rounded.
