Nozzlecam for the anycubic kossel!
Fits generic ebay 7mm (7.3mm) endoscope/borescopes.
Camera was less than 7$ from Gearbst/Bangood/ect. and appears to be 640x480 with around 4.5cm focus distance.
Note: there is only one lower screw hole on the hotend shroud, you can drill and tap your own or just place a short bolt with nut that fits in the fan and keeps part level.
