Door Knob Hole Cover / Plug — (No Supports)

Door Knob Hole Cover / Repair Plug — Clean Flush Finish (No Supports)

Got an old door knob hole, messy patch, or chipped paint around the lock area? This door knob hole cover is a clean, modern “plug + escutcheon” style cap designed to hide the opening and leave a neat finished look.

It’s a simple, functional print with a wide outer flange to cover imperfections, and a press-fit center insert that seats into the hole.

Dimensions

• Outer diameter (flange): ~75.0 mm
• Insert / press-fit diameter (main seating ring): ~53.2 mm (fits ~53–54 mm holes, depending on tolerance)
• Total height (overall thickness): ~14.15 mm
  • Main body thickness: ~11.15 mm
  • Raised rim height: ~3.0 mm
• Overall bounding size: ~75 × 75 × 14.15 mm

Features

• Covers old/unused door knob holes for a cleaner finish
• Wide flange hides paint chips, filler marks, and uneven edges
• Press-fit insert helps keep it centered and snug
• No supports needed (prints cleanly)
• Great for quick repairs, rentals, renovations, or hardware swaps

Best Use Cases

• Covering a door knob hole after changing locks/handles
• Hiding a rough cutout while waiting for a permanent repair
• Clean finishing touch for DIY door refurbishing
• Temporary cover for workshop/utility doors

Print Tips

• Orientation: print flat with the large face on the bed
• Layer height: 0.20 mm
• Walls: 3–4
• Infill: 10–20%
• Supports: None

Fit / Tolerance Tip

Door holes vary a lot. If the insert is too tight/loose:

• Try Horizontal Expansion in your slicer (±0.1 to 0.3 mm), or
• Scale XY only slightly (e.g., 99–101%)
