Prompt
Design a compact 3D printable manual paper punch tool with a hinged lever mechanism, similar to a single-hole punch, but adapted to create discbound (mushroom-shaped) holes. Structure: A flat base platform where the paper rests A hinged upper lever connected at the back with a pivot pin The lever should move downward to apply pressure Include a cutting punch element aligned with the base Cutting system: The cutting shape must be discbound style (mushroom / keyhole shape): rounded inner cut (6–7 mm) narrow slot opening toward the paper edge (3–4 mm) The cutting element must be designed to allow insertion of: razor blade segments OR a replaceable cutting insert Base features: Paper alignment guide (side and front stop) Slot or cavity under the cutting area to allow material removal Flat stable base for desktop use Lever features: Ergonomic top surface for hand pressure Internal structure to hold and press the cutting blade Reinforced hinge area Mechanical details: Use a pivot pin system (cylindrical hinge) Include space for a metal rod or printed pin Strong geometry for repeated pressure use Style: Functional mechanical prototype Clean industrial design Suitable for PLA or PETG 3D printing No decorative elements Dimensions: Small desktop tool (~10–15 cm wide) Compact and practical Important: The design must clearly show: base hinge lever cutting slot The tool should look like a real working paper punch Negative prompt Avoid: decorative shapes, toy-like design, unrealistic mechanisms, exposed unsafe blades, sci-fi style, organic curves, non-functional geometry
