I modified the screw part. This only contains the modified screw. I made the flat head smaller it was too big for my largest flat head(I could fit two inside).
You can use a butter knife to screw it in.

The main problem I had was the screw cached so when you pull the usb cable to unwind it unscrewed and well that is a bit of a pain. Over the past few days I have used mine vs the original screw. The original seems to unscrew and everything comes apart every-time I use it mine holds up a bit better and has never come loose for me.

Since this is just the screw part you can keep you printings of the other parts if you have already printed them.
