It would be helpful to include a photo like the one I'm attaching that shows how the main arm piece mounts the underside of the heating bed (including the space) and a photo with better resolution (maybe better light or a better camera) showing how the camera is attached to the main arm piece. It wasn't hard to figure out, but it would be a plus.

Also, consider updating the description on the main page to include a list of recommended parts/part sizes and consider changing the description to MK3/MK3S which this works for too.

The one potential design enhancement that I can recommend is making a small section of the part of the arm just below the bed wider on the bottom (maybe must add wings/rectangle shaped standoffs) so it is possible to zip tie the camera ribbon cable to the bottom of the arm without potentially damaging it.

What bolts are used to assemble the complete mount? Thanks and I apologize if I missed that information.

If I remmember correctly I used 2 M3x18 and 1 M3 nut from the spare bag of the prusa i3 mk3.

Works like a charm with the new extruder, thanks!

Thanks, this is perfect for the new extruder fan. However, I have a small issue. I removed the screw and spacer between the bed and the frame to then slide the printed arm onto, however this now leaves a gap between the part and the bed. The spacer won't fit back in as it will put a slight bend in the bed. Did you print your own spacer, or just stack on some washers to make up the space? Would be great if you could modify the arm part model to include a built-in spacer please.

I used the original spacer. The piece has a hole where spacer should fit without create any bend in the bed.
Would it work for you if I make this hole bigger?

Ah, silly me, I didn't think it would fit but it's perfect. I had to trim a bit of a bevel inside the arm to get it to fit and align the holes properly, but it's all secured now. Thanks for your reply and for sharing this mount.

You are welcome :)
Thanks for share your make.
