Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4716470.
After experiencing the awfulness of the CR-10 v2/v3 filament sensor location for myself, I opted to relocate the sensor onto the extruder carriage, immediately above the Titan direct drive.
This necessitated rerouting the filament sensor cabling to the carriage, at which point I opted to also create a cable chain for the extruder, see Thing:4716497.
I find this arrangement works quite well, with only a little bit of extra fiddling required to align the filament end for initial loading. This caveat is that you will lose approximately 15mm of Z travel (max Z is no longer 400mm, it is now 385mm).
This design utilizes four brass M3 heatset inserts (4mm long) for the sensor mounting and an option to add two more M3 inserts for additional expansions. If you opt to use the cable chain mount, it requires a fifth insert be installed on the left end of the bracket as viewed from the front of the machine when installed. I have attached a photo with the insert locations marked in orange. A sixth insert location is available for future expansion.
