3D Printable Parametric Hardware

A curated collection of 50 parametric 3D-printable hardware models. Knobs, hinges, clips, hooks, carabiners, fasteners, brackets, and specialty parts. Every model exposes customizable parameters (dropdowns, toggles, numbers) so you can dial in sizes and options to match your project.

What's inside

• Knobs and handles: star, T-handle, wing, knurled, skirted, cabinet pulls, tool handles
• Printable fasteners: hex bolts, wing nuts, thumb screws, T-nuts, captive nut inserts
• Hinges and latches: print-in-place barrel, pin, piano, living, slide, toggle, magnetic catch
• Hooks, carabiners, buckles: S-hook, J-hook, pegboard hook, side-release buckle, cord lock
• Brackets, spacers, mounts: L-bracket, shelf pin, hex standoff, GoPro, VESA, 1/4" tripod
• Specialty: cable grommet, under-desk cable clips, furniture feet, ball-and-socket mount, rod coupler

How these were made Generated on GrandpaCAD's AI pipeline as parametric CAD models. Each prompt specifies the knobs people actually want to customize (sizes, thread pitch, mount-hole spacing, clearances) using a mix of dropdowns, toggles, and numeric inputs.
