Prusa MINI filament sensor holder adjustable arm

Liked the original design, but my PTFE tube was probably shorter than the original arm was designed for so it didn't fit. Instead of just shortening it, I made it so that it is usable for a variety of lengths. The STL contains a sacrificial layer in the square nut slot that was designed for printing at 0.2mm layer height. No further supports are necessary. After printing just cut away the layer with an exacto knife. Use the bracket from Reso's design.
