Beskrivelse

Parametric Hardware System – Caps, Knobs, Protectors, Plugs & Washer Covers Description Create custom hardware covers, knobs, feet, shaft adapters, and washer-cover caps directly in the MakerWorld Customizer. This is a fully parametric OpenSCAD hardware system designed for metric nuts, bolt heads, acorn nuts, washers, motor shafts, and potentiometer shafts. Choose your hardware size, select the part style, tune the tolerance and dimensions, and generate the exact part you need. The Basic Dome Cap now also supports an optional washer-cover skirt, allowing the cap to hide not only the nut or bolt head, but also the washer underneath it. Perfect for furniture feet, exposed hardware covers, machine knobs, electronics projects, tool handles, jigs, fixtures, workshop repairs, and clean finished assemblies. ✨ What You Can Generate ✅ Basic Dome Cap Clean cover for exposed nuts, bolt heads, acorn nuts, or threaded hardware. Optional Washer Cover support adds a wider lower skirt that can completely hide the washer underneath the nut or bolt head for a cleaner finished appearance. ✅ TPU Floor Protector / Furniture Foot Wide brim protector for chair legs, table feet, threaded feet, and hardware touching the floor. ✅ Star Knob Classic hand-tightening knob with adjustable number of arms. ✅ Knurled Knob Round grip knob with textured outer edge. ✅ Wing Nut Knob Large easy-grip wing style knob with adjustable span and height. ✅ Daisy / Scalloped Knob Comfortable rounded grip knob with scalloped edges. ✅ T-Handle Knob Strong T-handle style part for tools, clamps, jigs, and fixtures. ✅ Screw Covers Low-profile covers for Allen / socket-head and flat-head screws. 🔩 Hardware Support The model supports metric sizes from M1 to M16 and several hardware types: Standard hex nut with bolt clearance Dome / acorn nut Flat bolt head D-shaft for motors Splined potentiometer shaft For compatible cap hardware, you can also enable the Washer Cover option. The washer pocket can use an automatically selected washer diameter based on the metric hardware size, or you can enter a custom washer outside diameter for non-standard hardware. You can also enable a side grub screw hole, useful for D-shafts, motors, knobs, and electronics projects. 🆕 Washer Cover Function The optional washer-cover system is designed for situations where a normal cap hides the nut but still leaves the washer visible. When enabled, the lower part of the cap automatically expands to create a wider skirt around the washer. You can control: ✅ Automatic washer sizing ✅ Custom washer outside diameter ✅ Washer clearance ✅ Wider protective lower skirt ✅ Smooth transition between the washer skirt and normal cap body ✅ Existing cap skirt length for additional thread coverage This makes it useful for furniture, machinery, outdoor hardware, exposed fasteners, and anywhere you want the complete nut + washer assembly hidden inside one printed cover. ⚙️ Parametric Features ✅ Metric size selection ✅ Press-fit tolerance control ✅ Adjustable wall thickness ✅ Adjustable skirt length for longer thread coverage ✅ Optional washer-cover skirt ✅ Automatic or custom washer diameter ✅ Adjustable washer clearance ✅ Adjustable washer transition / taper height ✅ TPU protector brim thickness control ✅ Custom knob diameter ✅ Adjustable base thickness ✅ Chamfered or rounded top edge ✅ Optional grub screw hole ✅ Star arm count control ✅ Wing span and wing height control 🖨️ Print Notes For rigid parts, PLA, PETG, or ABS/ASA work well. For floor protectors or flexible press-fit caps, TPU is recommended. Suggested starting tolerance: PLA / PETG: around 0.00 – 0.15 mm For a tighter press-fit, start around 0.00 mm TPU: around 0.00 to -0.10 mm For washer-cover caps, make sure the selected washer diameter matches the actual washer you are using. Standard sizes can be generated automatically, while unusual washers can be entered manually. Print orientation depends on the selected part, but most caps and knobs are designed to pr
