Keyhole Mounting Slot Negative Part Generator

Create customizable wall-mount keyhole slots with this parametric generator. Easily adjust entry hole size, slot width, depth, and length to fit different screw heads and mounting needs. Ideal for wall brackets, tool holders, picture frames, and other hanging applications. Supports both metric and inch units for flexible use. Designed for easy 3D printing and secure mounting, this tool helps generate precise, reliable slots tailored to your project.

Use:

1.) Generate and export the keyhole slot.

• Default settings are tuned for standard #6–#8 drywall screws.
• If switching from metric to inch units, note that the existing metric dimensions will scale up significantly until adjusted.

2.) Insert the keyhole slot into your model as a negative shape to prevent material printing in that area.

--OR--

Use a boolean operation:

• Import the slot as a solid part.
• Align it to your model.
• Use Mesh Boolean → Difference to subtract it from your design.

3.) Print your model.

• These keyhole slots typically print well with little to no support required.
