Printed all in PLA plastic, at 0.2mm layer hight without any weird parameters, the normal profile on your printer should do the job perfectly.

Notes:
-Created a hole inside both blades so you can fit a threaded rod or a wood stick, the diameter of the hole is 8.3mm so any M8 rod or 8mm wood stick sould go in without resistance.

-the orientation of the pieces is pretty straight forward, the only problematic parts are the handles, maybe you will have to print them in 2 parts.

-I`ve included the complete model for doing a miniature of both daggers and the splitted version for doing the bigger (important, for the splitted version you will need the 3mf extension on your slicer)
