About this 3D model

Technerd's original ultimate nozzle works much better than the OEM, so I recommend it. But as @zlkent noted, it can break from use. It takes a beating from the printhead. This is because the vertically printed small pin is weak due to breaking between layer lines. This remix makes the pin stronger by printing it in the X-Y plane, so the lines go up-down the pin, not across. This is much stronger and doesn't require a miniscule screw to provide the strength. To get a nice print, the pin is a hex, not round, and other tweaks make a reliable no-support print. Use the 3x5mm silicon tube available directly from BambuLab Store (see BOM below), or buy 3x7mm elsewhere. Use PETG or ABS/ASA if you have it, for strength and temperature tolerance in an enclosure. I printed PETG at .24 layer.
