My main side gig is photography.
One of my cool toys is a Nikon 400mm f/2.8 lens. Big lenses like this typically use a clamping screw arrangement to secure the lens hood in place, which I don't like. It's not real secure and it's a bit fiddly getting the hood on the lens. I've had my hood fall off the lens 3 times while walking around. A replacement hood is about $600 US, and a hood that is in good shape is good for resale value.
So I decided to see if I could design and print a decent replacement. I got to a decent baseline pretty quick, but there have been a lot of little tweaks. I'm printing with 3DXTech glass-filled ABS using a ruby nozzle. My printer is an N2 with a Duet2 Wifi controller board and bondtech extruder. I've also added heat to the box and these are printing in a 55C enclosure.
I've cleaned up the retraction so I'm now printing with random starts to eliminate the zipper.
These hoods can be mounted reversed for storage.
Show off your prints, mods, etc.
