J-Nozzle 1" Extender

thingiverse

This extension piece fits over a standard J-Nozzle, increasing its length by an inch. Adjustable in OpenSCAD (rev 03), you can change the extension height and filament hole diameter to match your requirements. Print at high temperatures for strong layer fusion; drill the end of the filament tube if needed. ABS works well, with acetone vapor bath for enhanced fusing. The top hole taps M10 x 1.0, maintaining compatibility with the J-Nozzle's threading. Used for replacing an Eventorbot hotend with a MKV clone, this extender ensures proper fit in the same bracket.
