RaspberryPi Camera Focus Screwdriver (short)

Absolutely based on the RaspberryPi CameraV2 screwdriver by ascii_ch (Thank you)...

When I put his model on my slicer I thought it was unnecessarily tall, so I imported the stl into Blender, duplicated it... cut the top of one, the bottom off the other and then merged the two halves back into one model...

There is probably an easier way to do this, but at the moment my capabilities in Blender are restricted to Boolean operations and as of today, the Bisect function!!

All videos on Internet about the Raspberry Pi camera either tell you it's a fixed focus camera (true, it comes with blobs of glue holding the lens) or they tell you to remove the blobs of glue with a sharp implement and then focus using a pair of pliers...

Obviously that make a bit of a mess of the housing and this tool is a much more elegant solution... You now have the options of a long tool (ascii-ch's original) or if space is tight, my modification!

You shouldn't need a raft to print this 'Thing', espec
