BIQU H2 7mm Inspection Camera Mount

This model is FAR from perfect.  It works, but consider it a first draft.  There are quirks, and I'm not confident it'll handle accidental bumps well at all.  As you may be able to tell in the photos, some of it is just wonky.

Included is the FreeCAD file.  It is a bit of a mess, but work-able.

This is designed around a 7mm inspection camera (you want one with a flexible cable - many have a wire in them to stiffen them up).  I suspect it would work with an 8mm inspection camera, but I think you'd want to tighten it up in FreeCAD if you wanted it to work with a 5mm inspection camera.  I don't suggest a 5mm camera.  Larger has in my experience meant better quality image.

I used:
- 2x M3 threaded inserts (less than 5mm long)
- 3x M3 10mm
- 1x M3 16mm (20mm might work too - have not tested)

The one I'm using here:

The camera's real diameter as I measured is 7.49mm - This may help you identify if the mount will fit the inspection camera you may already have, since the listing for the one I got won't be around forever.

It is okay.  Not amazing, but it works fine for me.

The mount is attached with standoffs from the toolhead because otherwise it would block airflow from the fan that helps to keep the extruder stepper cool.  I have a better way of doing it, it just takes more effort than I had in me for a quick proof of concept, just to figure out what angles I'd want to mount the camera at.  Odds are I'll keep running this as is until it breaks, but its possible I'll completely redesign it several times since its a quick print to iterate on.

There are three components.
The long base that mounts to the toolhead, which gets an insert, the middle arm, which also gets an insert, and then the camera clamp.

Print the base standing up like a rocket, with bed supports.
The middle arm can be printed in various orientations, no supports.
The clamp should be printed on its side, no supports.
Everything needs to be printed at 100% infill.
I printed it in PLA.

A WARNING: This camera when the LEDs are left on high for extended periods gets fairly hot.
I don't know if the PLA will soften from the heat enough to cause problems.
EDIT: I have several hundred hours of print time on it now, and have not had a problem.  I turn the LEDs off when not in use to hopefully extend the lifespan of the camera.  Parts cooler tends to keep it from cooking itself when running.

There is now a cap, to cover the lens:
