Custom Handle Generator for 3D Printing

Hole spacing is one of the most important dimensions for a furniture pull. It is measured from the center of one mounting hole to the center of the other.

When replacing an existing handle, measure the mounting-hole centers first. You can also remove the old handle and measure its fixing points directly.

Vuolti lets you use that exact spacing as a design parameter. This means you do not need to drill new holes in the furniture just because a replacement pull uses a different standard spacing.

• always measure center to center
• use the old handle as a reference if helpful
• do not confuse hole spacing with overall handle length
• check the diameter or thread size of the existing screws
• print one test handle before producing a full set

Many furniture pulls are sold in common standard spacings, but older furniture, custom cabinetry and imported hardware often use different measurements.

A parametric generator is useful because the handle adapts to the existing mounting pattern instead of forcing the furniture to adapt to a standard product.

It is equally useful for new furniture when you want to choose your own spacing from the start.

Hole spacing defines the mounting points, but it does not define the entire shape of the handle.

Overall length can be adjusted independently, controlling how far the grip extends beyond the posts.

Depth and height determine the grip cross-section and influence both appearance and feel. A slim grip looks more minimal, while a larger cross-section can feel more substantial in the hand.

Corner radius controls how sharp or rounded the outer form feels.

A small radius creates a straighter, more technical look. A larger radius produces softer transitions.

Rounded edges can also feel more comfortable on a handle that is used frequently.

Finger clearance controls the space between the handle and furniture front.

Too little clearance makes the pull uncomfortable to use. Too much can make it project unnecessarily far from the door or drawer.

Consider not only the visual size of the handle but also how much room your fingers need when opening the furniture.

Larger hands, work gloves or thick drawer fronts may benefit from additional clearance.

The ends of the grip can use different shapes. Depending on the selected style, options can include chamfered or more rounded ends.

The length of the shaped end region can also be adjusted.

This allows the same basic grip to range from a clean, straight design to a softer and more styled form.

A flat back helps the mounting posts and handle sit cleanly against the furniture front.

This is especially useful for drawers, cabinet doors and other flat surfaces.

Depending on the selected style, additional contour controls may be available for shaping the grip body.

The posts connect the grip to the furniture and create the finger clearance behind it.

Post diameter can be adjusted to suit the visual proportions and available material around the screw seat. Tapered posts can also be enabled.

A larger post looks more substantial and provides more material around the mounting area. A slimmer post creates a lighter visual appearance.

Actual strength also depends on filament, print orientation, screws and print quality.

Tapered posts change cross-section between the furniture front and the grip.

This creates a smoother transition than a purely cylindrical post and can provide both visual and structural benefits.

Depending on handle size, tapering can also place more material near the connection to the grip.

Not every drawer or cabinet needs a two-point handle. Smaller doors and drawers often work better with a single furniture knob.

The Handle Generator can also create knob variants. Depending on the selected style, knob shape, diameter, height and neck dimensions can be adjusted.

This makes it possible to create knobs for drawers, nightstands, dressers and small cabinet doors.

For a knob, diameter and height are the main dimensions.

A larger diameter provides more grip area, while a smaller knob looks more subtle. Height determines how far the knob projects from the furniture and how easily it can be grasped.

Neck diameter also matters because it defines the connection between the knob and mounting surface.

Furniture handles are typically fastened from the rear of the door or drawer front, so the screw and the internal seat need to match.

The generator lets you select a suitable screw size and configure the screw seat.

Depending on the hardware, this can include a countersunk seat or a cylindrical counterbore.

Check the actual screw dimensions before printing and test the connection on a single handle first.

A countersink is a conical recess designed for a countersunk screw head.

A counterbore is a cylindrical recess for screw heads with a flat underside.

The correct option depends on the screw being used. The digital seat geometry should always match the real hardware.
