Screw Anchor

This printable screw anchor set includes four plug sizes: 6 mm, 7 mm, 8 mm, and 10 mm, suitable for various wall types such as concrete, brick, or drywall. Each anchor is designed to fit screws approximately 2–3 mm smaller than the outer diameter of the plug — ensuring solid expansion and tight grip. 

Dimensions: 

• 6 mm plug → best with 3–4 mm screw 
• 7 mm plug → best with 4–5 mm screw 
• 8 mm plug → best with 5–6 mm screw 
• 10 mm plug → best with 7–8 mm screw 

Recommended to use Petg, ABS or nylon (less brittle than PLA) for optimal functionality. 

These anchors are easy to print and strong enough for most household tasks like mounting shelves, hooks, or small cabinets.
