Any "macro" cameras?

[Xeddog]

I have a newly acquired 3D printer and a spare port on my NVR (DaHua NVR5216-16p-4ks2), so I thought it might be kinda fun to put a camera on the printer so I could monitor the progress of prints via the NVR. I know this isn't a very good use of a security system, but what the heck. I have all I need except a camera.
None of the cameras I have will focus at the 1 foot or so distance required, so I just thought I'd ask here if anyone knows of a IP camera that will focus down to a foot or possibly even a little less. It doesn't need to be PoE since power will be available, but it would be preferred. It does need to be IP, and CHEAP, and the smaller the better.

All suggestions welcome,

Wayne

P.S. I posted this in the DaHua section since I would prefer a DaHua camera, but I am open to any brand.

Hikvision do that micro cam that fits into ATM machines comes with an long lead from the camera and also different mm lens options there ok.

If you use a simple fixed-focus camera and unscrew the M12-type lens partway, you will move the focus in closer. I would think you could probably make it focus down to 1 foot. I have replaced the factory-stock lens on two Dahua IPC-HDW4431C cameras so it is possible to do. Next best thing under 100$ to Starlight Varifocal Turret (IPC-HDW5231R-Z)
