Heavy-Duty Utility Knife - the Smallest EDC cutter

World's Smallest heavy-duty EDC Utility Knife design This is my original design of the heavy-duty utility knife, engineered to be as small as physically possible.  The shell barely covers a standard Stanley blade, making it the most compact practical pocket cutter you can print. ✨ Key Advantages Heavy-Duty Design: Optimized for strength and daily cutting tasks. Compact Footprint: Barely larger than the blade itself. Easy Blade Swaps: Simple to assemble and take apart—no tools or glue needed. Built-in Line Cutter: Quickly slice string or clothing tags without extending the blade. Ambidextrous: Symmetrical shell works equally well for left- and right-handed users. Zero Supports: 100% support-free print. 🔩 Required Hardware 1x Standard Utility Knife Blade ('Stanley 1992’ / trapezoid blade) ⚙️ Print Settings (Important!) This model is Optimised for PETG or PETG-CF filament, and tuned specifically for the dedicated print profiles. Nozzle: 0.4 mm Layer Height: 0.20 mm (including the first layer) Supports: None ⚠️ Note: Changing the layer height (e.g. to 0.16mm) or nozzle size will alter the internal tolerances and cause fitment issues.  ⚠️ Safety Handle sharp razor blades with care. Keep out of reach of children.
