Star Postbox | 星邮小站

圆角星章邮筒与可取出的装饰信件，共两个独立零件。本页提供两个分件STL和一个通用彩色3MF。分件信件STL已背面朝下；通用3MF保留信件半插入的装配展示姿态，不是打印排版。当前展示位置最小数字表面净隙约0.96 mm，信件可竖直拔出并插回。再向下约1.17 mm时，凸起装饰会碰到槽口前沿形成限位，不能插到底，请勿强压。上述为数字几何测量，实体配合未经测试。 尺寸：邮筒 / Postbox: 58.93 × 38.94 × 84.78 mm; 信件平放 / Letter laid flat: 24.99 × 21.98 × 4.79 mm (X × Y × Z) 邮筒直立，信件单独平放背面打印，并在切片器中重新排版。检查邮筒悬垂与槽口薄边，拆支撑要轻柔。先试配并按设备公差调整，不要未经检查整体缩小。不是儿童玩具或食品接触件。 本页模型文件：star_postbox.stl、removable_letter.stl、star_postbox.3mf 封面为基于实际模型参考图生成的AI数字场景，辅助检查视图为实际几何渲染，均非实物照片；尚未实体试打。本页模型下载仅含所列STL和通用3MF。STL无颜色；通用3MF包含几何与显示色，不是切片工程，也不是打印机即用文件。独立Orca参考工程不在本页提供；本页也不附Blender源文件、生成脚本或G-code。打印前请按自己的机型、耗材与供料槽检查颜色和支撑，并重新切片。 原创设计及署名：TechABJ / 理工阿白菌。许可：CC BY-NC-SA 4.0，署名、非商业性使用、相同方式共享。请保留作者署名与作品名称。 A rounded, star-badged postbox with a removable decorative letter, supplied as two separate parts. This page includes two part STLs and one generic colored 3MF. The individual letter STL is already laid on its unadorned back. The generic 3MF retains a half-inserted assembly display pose, not a print layout. Minimum digital surface clearance in that pose is about 0.96 mm. The letter can be lifted out vertically and returned to that pose. About 1.17 mm of further downward travel brings its raised decoration against the front slot lip, forming a stop. It cannot seat at the bottom; do not force it. These are mesh measurements, not physical fit tests. Dimensions: 邮筒 / Postbox: 58.93 × 38.94 × 84.78 mm; 信件平放 / Letter laid flat: 24.99 × 21.98 × 4.79 mm (X × Y × Z) Print the postbox upright and the letter separately on its back, arranging both in your slicer. Inspect overhangs and the thin slot lip, and remove supports gently. Test-fit and adjust for printer tolerances. Do not scale down without checking the slot and details. Not a children’s toy or food-contact part. Model files: star_postbox.stl, removable_letter.stl, star_postbox.3mf The cover is an AI-generated digital scene based on actual model reference renders. The inspection views are renders of the actual geometry. None are photographs of physical prints. No physical print test has been performed. Model downloads on this page contain only the listed STLs and generic 3MF. STL has no color; the generic 3MF carries geometry and display colors, not a slicer project or printer-ready file. A separate Orca reference project is not included on this page. Blender source files, generation scripts and G-code are not included here. Set up your actual printer, materials and feeder slots, inspect colors and supports, and re-slice before printing. Original design and attribution: TechABJ / 理工阿白菌.
