UM2 Fan Shroud Nozzle Cam - Endoscope / Otoscope Search

[OPC 2]

Hi,

First time posting. I designed a nozzle-cam fan shroud for my UM2 extended but am having trouble with the endoscope focusing on the nozzle due to the focal distance.

Design can be found here, pictures should be attached.

The design mounts the 8mm soft cable endoscope around 25-30mm away from the nozzle, but the only endoscopes I can find have a focal distance of around 60-100mm.  Even at that distance I had to decrease the build volume around 20mm or so, so the end of the camera wouldn't collide with the interior walls of the printer.

 

Does anyone know of an endoscope with the same sorta size package as the one shown / linked below that has a shorter focal distance?

I know there are some otoscopes, or an ear endoscope, but they all seem to come with a 200mm pole, not really suitable for my design.

& not really looking to rip apart the endoscope if I don't have to.

 

Figured i'd make my first post and ask the community.

I've uploaded a few video's to my website if you'd like to see it in action, besides the blur, its pretty cool!

(Note: the design was based off a fan shroud I found I think on this forum, & think it was originally designed by @Labern)
