Description
PDF| Note: Use the V2 printer clip. I realized that the filament sensor going down was limiting the printer's ability to print above Z200, as such I've essentially flipped the mount so now the sensor sits above the gantry cap. |
I forgot print in place parts exist, but this snaps in fairly well so yeah.
You will need some sort of lubricant, I used dry PTFE, and it's moving really smoothly. You could iron the top surface of the sensor mount in order to smooth out the top surface that's going to be rubbing against the stationary mount.
To mount the sensor in place, you can use either of the two models supplied. One is designed for the screw to go directly into the plastic with a 0.2mm tolerance, one designed to use M3 4.2x3mm threaded inserts.

Model origin
The author remixed this model.
Differences of the remix compared to the original
Added a pivot point for the sensor to move with the filament, in order to put less strain on the filament, potentially preventing some fragile ones from snapping mid print.
