3d print model for a naginata / spear tip.
~ 500mm long,fits on top of a 30mm diameter pole.
For smaller 3d printers, I divided the model into 4 pieces (almost no support needed).
The sections can be put together with Dowel Pins (8mm x 40mm) to provide extra strength.
NOTE! On the last photo, the spear might look a bit misaligned cause I was impatient with taking the picture, the 2 sections were not connected properly yet :P
