Guessing Aluminum from topic title, if using strong steppers like the Nema17 76oz one’s V1E sells in the LR3 kit, consider leaving the front Strut solid, save on cut and cleanup time without adding much weight. Personally like look of a solid front grill. a solid diamond panel for front grill would look slick. For easier life, recommend assembling struts in sequence… bottom, front, then rear.
