Reflex Hammer (Tromner style)

Tromner style neurological reflex hammer Created for fun to experiment with different filament properties (density, flexibility, etc.) but fully functional (and despite the light weight, still works better than the crappy tomahawk shaped ones).
Requisite disclaimer that this should probably not be used as an actual medical device (i.e. use at your own risk). Though a reflex hammer should generally not get significantly soiled (otherwise you are using it wrong?), it is likely inherently impossible to properly sanitize/disinfect a FDM 3D print with all of its gaps/holes between surface layers.
