Adjustable arm for camera

This is an adjustable arm that can support, among other things, a webcam for a raspberry pi running Octoprint. The design is optimised for printing as I have seen lots of designs with thin parts that need support. This design needs support for only a small bit of 2 parts: the hole in the 90 degree twist and the hole in the V slot connector. You could probably print this without support without issue,

The arm has a base that bolts to a V Slot or T Slot with an M3 hole. I suggest using https://www.thingiverse.com/thing:3050607.

There is a long (60mm) and short (30mm) arm, rotating arm that uses an M3x12 screw and plain nut that can rotate 360 degrees, although, I would suggest +-90 degrees.
