Prusa MK3 NozzleCam

This is a multi-part design for a somewhat adjustable 5.5mm nozzle camera which can be mounted to the extruder carriage of a Prusa MK3. The STL contains all required parts, including a modified extruder cable holder, an adjustable boroscope holder, and some cable clips for guiding the borosocpe cable along the extruder cable bundle.

The borescope mount is somewhat adjustable to ensure the camera does not collide with the heatbed cables whilst keeping the nozzle as good as possible in frame.

To mount the boroscope to the extruder cariage, the cable holder was slightly modified to contain a slot for an m3 nut, as well as sligth printability improvements and an increased cable exit angle.

In my assembly it just clears the heatbed cable cover, so his is something to look out for before starting a new print. However if clearance is too tight the height of the camera can be somewhat adjusted.

Assembly of these part requires one m3 nut and one 10mm m3 bolt. These should be available in the spare parts bag of the MK3 kit.

This model is intended to be printed in PETG as the camera can get quite warm and it will be close to the heated bed.

During mesh bed leveling the NozzleCam may catch on the heatbed cable cover. To fix this I also made a very low profile heatbed cable cover, which can be found here:
