This is a replacement nozzle and replacement nozzle cap for Super Glue/CA Adhesive bottles. It's possible multiple brands use this type, but this one was specifically modeled after the Rockler/Stick Fast brand, for the 4.5 Oz bottles.
In the photo, the printed cap (black) is on the left, and the original (blue) is on the right.
Note!
The “nozzle” file has a support cylinder built into it. The files are already oriented in their ideal direction. Do not split the nozzle file into “objects” in prusa slicer, or it might move the support cylinder off position (though splitting into “parts” is fine, and probably a good idea).
