This bracket holds in place the reverse bowden tube.
Require an M3 bold and M6 passthrough connector. You can use one or two.
The lower one is slightly loose but does the job.
No support needed (printed with the thread on the build plate), 3 or 4 walls.
10% infill.
Thanks to Pavel for the Filament Runout sensor design.
