Stag - 3D Printed OTT/TTF Slingshot

Stag is a 3D-printed slingshot inspired by the shape and powerful presence of a stag beetle. Like a stag beetle ready to strike, it combines the hardness of an insect shell, the tension of biomorphic design, and the practical structure of a handmade tool. That is why it is named “Stag.”

This slingshot features 25 mm wide fork tips, making it compatible with most common slingshot bands. The large central U-shaped opening provides excellent projectile compatibility, making it suitable for clay balls, fishing darts, and larger stones.

Both fork arms use a side-inserted nut structure designed for M5 nuts. This improves fastening strength while giving the overall form a thick, stable, and geometric appearance.

The fork tips support both OTT / Over-the-Top and TTF / Through-the-Forks band setups. For the OTT setup, the bands can be secured with zip ties or amber bands, or used together with printed clamps. The TTF setup requires the corresponding printed clamps.

The handle incorporates shell-like rounded contours and flowing transitions, creating a balance between mechanical structure and organic form. Its grip is especially suited for a push-grip shooting style, offering solid and stable support. The lower handle continues the hard and powerful visual language of the stag beetle. It fills the palm well and provides a full, comfortable grip.

Overall, the design combines functionality, structural strength, and sculptural character. It is both a practical 3D-printed slingshot model and a personalized biomimetic design inspired by insects.

锹甲 Stag 是一款以锹甲虫外形与力量感为灵感设计的 3D 打印弹弓。它像一只蓄势待发的锹甲，将昆虫甲壳的坚硬感、生物造型的张力，以及手工器械的实用结构结合在一起，因此取名为“锹甲”。

该弹弓采用 25 mm 宽大的撑头设计，能够适配绝大部分常见皮筋。中央 U 形大开口提供了较高的弹丸兼容性，可用于泥丸、鱼镖以及较大尺寸石子的使用场景。两侧叉头采用侧向嵌入螺母的结构设计，适配 M5 螺母，在增强固定强度的同时，也让整体造型呈现出厚实、稳定的几何块面感。

撑头同时支持过顶试和穿叉式两种绑法。过顶绑法可使用扎带或琥珀带固定皮筋，也可搭配打印夹片使用；穿叉绑法则需要配合对应夹片。握柄部分融入甲壳般的圆润隆起与流线型收束，使作品在机械感与生物感之间形成平衡。其握持姿态更适合虎口推握弓法，支撑感扎实稳定。下方把手延续了锹甲坚硬、有力的造型意象，能够充分填满手心，握感饱满厚实。整体设计兼具功能性、结构强度与雕塑感，既是一款实用的 3D 打印弹弓模型，也是一件带有昆虫仿生风格的个人化造型作品。
