Holder for the Palette+ filament sensor. Can be screwed on to the backside of the D6 printer. Use the longer screw that came with your printer.
Print both parts and glue them together. I used CA for this job.
Printing two separate parts, eliminates the use of supports.
The sensor-holder itself, is a remix from: https://www.thingiverse.com/thing:2659054
Added a new version of the sensor-holder with a hold-back extension.
Maybe, you will like the Palette+ tubeholder for the extruder too: https://www.thingiverse.com/thing:2798204
