Has a hole for a 3mm rod down the middle, might be able to use a 1/8 inch rod but check each hole before assembly or scale up slightly. The small alignment holes are for filament.

There are 2 versions of the scabbard one which I used and lined the inside with felt but it is much harder to print and an easier version. I included my felt pattern in a zip file its not perfect but gets you close cut inside the lines. If you go with the lined scabbard I recommend getting rid of layer lines on the top detailed part before assembly so you don't have to worry about masking off the lining and have a easier time wet sanding. For the easy version of the scabbard I've included two alignment rings.

Part of the crossguard has print defects due to overhangs but its easy to clean up with spot putty and sanding as its on a flat area.
