These brackets allow you to use a reverse Bowden tube to stop the filament from pulling on the extruder and giving inconsistent extrusion. This increased print quality significantly for me.
Designed to be used with either my Neptune 4 filament roller upgrade or an off printer spool holder of some sort.
There is a pilot hole to mount the sensor, but I prefer to have the sensor sit loosely in the bracket as to not over constrain the system.
Hardware required:
- 3x PC4 M10 Fittings (Thread is actually 1/8" BSP)
- 2x M5x20 Screws
- 2x Printable (and included) m5 t-nuts
- 2x M3x20 Screws
