On my davinci jr, I replaced the Bowden feeder and mounted it outside the unit. There is a filament sensor that is in the stock feeder that I wanted to keep. I also wanted my Raspberry Pi to be mounted inside the unit so I created this bracket.
There are two versions of this. First is a solid bracket, and the other is honeycomb.
This is designed in openSCAD.
Thanks to EvanCarlsen for the honeycomb generator code in https://www.thingiverse.com/thing:1652822 that I used and to mattjoyce for his parametric 90 degree code in https://www.thingiverse.com/thing:2366480 that I used.
