Mossberg 500/590 Forend

For an original look-and-feel, print in woodfill PLA. For maximum sturdiness I chose 5 perimeters and 50% infill. Organic supports where needed. 0.6mm nozzle height and 0.25mm layer height works great.

I've experimented a bit with the filament. I got the best results (also color wise, to fit the original wooden stock) with extrudr Dark Wood.
