Sample Spool Holder Arm (Tall Remix)

This is a remix of the Filament Sample Spool Holder by FilamentColors.xyz (www.prusaprinters.org/prints/38041-prusa-mini-sample-spool-holder). I am using this mount on my Prusa Mini to attach the to the vertical 3030 rail.

I installed the Filament Runout Sensor Holder (www.thingiverse.com/thing:4582929) but soon found that this made the sample spool holder un-usable because the sensor now interfered with its rotation. So I remixed the holder arm to make it tall enough to clear the addon run-out sensor holder arm. I had to make to 10mm thick, which seems like overkill, but the prototype was 4mm thick and it broke off when the filament had a small snag because the layers ran horizontally causing it to be too weak.
