The Delta-P Duct is an awesome concept. While there are already designs for fitting an endoscope camera, I wanted a system where the camera could be easily removed without disturbing the extruder cooling and restore the excellent view of the nozzle from the front.
This allows the printer is quickly ready for use, with or without a camera fitted.
Two M3x12 screws with DIN562 thin square M3 nuts can hold a variety of camera adapters. A 3.9mm endoscope adapter is the one I am using.
The camera adapter require one M3x10 screw and standard nut for the clamp.
A modified model of the duct has two thin nuts added.
These, and the existing nut, are set up for an easy press fit for nut 1.79mm thick nuts, sourced from:
Prusa nuts, typically 1.7mm will fit just as well. If you have out-of-spec “thin” square nuts, up to 2.2mm thick, the nut slot will have to be opened up.
Why not just open the slots to accept all nuts, including 2.2mm thick nuts?
If you do that and fit nuts that are in spec, they fall out when the part is inverted.
I have posted model files as well to allow adjustments to be made.
The 3.9mm endoscope is more expensive but none of the other types; 5.5mm, 7mm, 8mm etc, have as good an image. I have tried them all.
The 3.9mm endoscope with one metre cable was sourced from Aliexpress.
The most common cable is semi-rigid. I did notice when trying the semi-rigid cable, it does stress the extruder slightly and forces a really tight clamp to be used. So I use the soft cable. To stiffen it a bit, I have wrapped the cable in thin spiral wrap and that seems to stop the soft cable flopping around.
I have posted an image of the 45” full screen I use with the 3.9mm endoscope.
