This would be very welcome. Groovemount has always bothered me as it's a pain to take apart. I broke one way back as well. I had made an intermediary solution like this; And that was locked very, very tight. So, screw like lightbulb should be a tool, not a goal in itself, I kinda agree with the clamp options.
The Duet3D smart delta effector and custom heatsink (manufactured for us by E3D) are now available to buy at https://www.duet3d.com/DuetAddons/DeltaSmartEffector.
Any update on the threaded heatsink. I have a use case for this kind of mounting option on a printer I am overhauling. Thank, Matt
Was there any new feedback on the threaded heatsink. Anybody run into any issues? https://e3d-online.com/v6-threaded-heatsink
Mine mounted onto the Smart Effector with no issue, but I haven't finished building the big delta printer that it's intended to go into, so no idea how well it will work out. I've seen some discussion about it over on the duet3d forum though, if you want to read up on it over there.
