Precision-cut 1515 aluminum extrusion frame kit for Printers for Ants Micron builds. Choose the 120mm or 180mm build size and the anodized color that matches your project. Why this kit Built around the official Printers for Ants Micron R1 frame BOM instead of a generic extrusion bundle. Uses 1515 frame extrusion geometry for the compact Micron platform. Available for both 120mm and 180mm Micron build sizes, with color-matched frame options. Specifications Project fit: Printers for Ants Micron / Micron R1 frame builds. Profile family: 1515 aluminum extrusion; the official BOM references Misumi HFS3-1515 frame members. 120mm build BOM lengths: HFS3-1515-300 x4, HFS3-1515-220 x10, HFS3-1515-205 x2, HFS3-1515-190 x1, HFS3-1515-120 x1. 180mm build BOM lengths: HFS3-1515-350 x4, HFS3-1515-280 x10, HFS3-1515-265 x2, HFS3-1515-250 x1, HFS3-1515-180 x1. Variant choices: 120mm or 180mm frame size; Hot Pink, Purple, Black, Space Grey, or White finish. Build fitment Use this as the structural frame set for a Micron build. Pair it with the Micron Motion Kit, Micron Motors Kit, Micron Wiring, Electrical and PCB Kit, and No-Drop Nuts for European Standard 1515 Extrusion when you are filling out the rest of the machine hardware. What this is not Not a complete printer kit. Does not include rails, panels, motors, electronics, printed parts, fasteners, or bed hardware unless explicitly selected elsewhere.
