6 PCS Diagonal Rod 210mm M4
This 6-piece Diagonal Rod set is designed for Delta-style 3D printers, providing the essential linkage between the carriages and the effector platform. Each rod measures 210 mm in length with M4 threaded ends, machined for precision and consistency to ensure smooth, accurate motion. Ideal for Kossel Mini, Kossel XL, and other Delta 3D printer builds, this matched set guarantees identical rod lengths — a critical factor for accurate print geometry.
طقم قضبان قطرية مكوّن من 6 قطع مصمم لـالطابعات ثلاثية الأبعاد من نوع Delta، ويعمل كحلقة الوصل بين العربات ومنصة الإفكتور. يبلغ طول كل قضيب 210 ملم بأطراف مسننة M4، مصنوع بدقة عالية لضمان حركة سلسة ودقيقة. مثالي لمشاريع Kossel Mini وKossel XL وغيرها من طابعات Delta. يضمن هذا الطقم المتطابق تساوي أطوال القضبان، وهو أمر بالغ الأهمية للحصول على هندسة طباعة دقيقة.
These Diagonal Rods are a critical mechanical component for any Delta-configuration 3D printer, forming the six-arm linkage system that connects the three vertical carriages to the central effector (hotend platform). The geometry of a Delta printer depends entirely on the precision and uniformity of these rods — even a fraction of a millimeter difference between rods can cause distorted prints, uneven layers, or geometric errors.
This set includes 6 matched rods, each measuring exactly 210 mm in length with M4 threaded ends ready to accept standard Delta-style ball joints, traxxas-style rod ends, or magnetic ball mounts. The rods are precision-cut to ensure all six pieces in the set share identical lengths, eliminating the need for manual measurement and pairing.
Delta 3D printers rely on the synchronized movement of three pairs of these arms — when the carriages move up or down along the vertical towers, the diagonal rods translate that motion into the X, Y, and Z positioning of the print head. The result is the famously fast, smooth, and precise motion that Delta printers are known for.
This set is compatible with popular Delta builds including the Kossel Mini, Kossel XL, Anycubic Kossel, Mini Kossel, and other DIY Delta designs that use the 210 mm rod length specification. Whether you're building a new Delta printer from scratch, replacing worn or damaged arms, or upgrading an existing machine for better print quality, these rods provide the reliability and accuracy you need.
