Boscam FR632 is a nice diversity video receiver. I wanted to mount it in a semi-permanent way while maintaining the possibility to move it. I am not a great fan of slapping Velcro to my equipment, so I designed a custom holder instead.
The yellow line close to the bottom was an experiment. I wanted to add some variation to the looks of the holder. The line is not part of the STL file and the print does not require dual extruders.
To make the line I just paused the print, switched to yellow filament, printed for a while and then switched back to black. Quite easy, I will use the technique again.
