Two piece, glue together, prints in any rigid material, I used PLA. Paint-on Support suggested only for the connector tab as show in image.
I suggest 5 or 6 perimeters and 25% gyroid infill.
If you open the Fusion 360 CAD file you can adjust the spikes using supplied parameters.
Use glue (CA) to attach handle. Use a lighter or torch to adjust sharpness of spikes to taste.
