A dagger I designed for a family member, based on the dagger carried by the Paedyn Gray character from the Powerless book series by Lauren Roberts. 

The blade is designed to be printed in translucent PETG and there is a scroll design inside the blade (see second picture). The handle consists of an upper and a lower scale with two pegs. These can be printed in PETG or PLA, though I opted for silk silver PLA.

Use slim tree supports in critical areas for the top handle. There will be a warning for unsupported areas for the bottom handle, which can be ignored.
