Remodelled official Bondtech BMG Creality CR-10S mount.
The issue with the standard mount is that when the end of the filament passes the sensor, it is difficult to remove the piece of filament still in the bowden tube without a lot of messing about. The extended sensor arm allows easy access to the end of the filament after it has passed the sensor switch.
It also stops the BondTech destroying the switch when using it to unload the filament.
Grab the end of the filament from the gap between the sensor and the extruder and unload by your preferred method. Much easier.
I also removed the need for supports under the sensor block during printing and increased the clearance in the filament path for the sensor switch, as the latter's lever arm can foul on the top of the chamber..
Please note: I give Full Credit to Bondtech for their original design. All I did here was a remix.
For your convenience, the reduced support version of the standard Bondtech BMG mount is also included, as is the unmodified Sensor Cap Plate.
You no longer need infill under the sensor block (to the bed), support is advised elsewhere, although not strictly necessary.
Infill is not critical as apart from the extended sensor arm version there is no real load on the bracket. Suggest a bit more for the extend arm in case you give it a hard knock or lean on it.
General cleanup and support removal.
Uploaded the original Bondtech CR-10S file (Creality CR-10S Mount.stl) for conversion into Fusion 360.
Converted the mesh body to a BRep, then sectioned the object, repositioned it and reconstructed a solid arm between the two parts.
Matched the surface facets and tidied the objects up.
Saved as STL files.
