prints as one piece, use a brim, infill should be about 60-100 percent for strength. the overhang for the outlet holes may be too shallow but a little stringiness is okay, trim it off with an exacto knife, the harmonica rests inside and should be held in with glue, hot glue works best. the hole accepts a 9mm arrow shaft. This arrowhead is kind of heavy so be careful using high powered compound bows. i launch mine with a low powered re-curve crossbow. have fun and be safe!
