Custom Golf Ball Stencil and Alignment Line Generator

What you get

A printable cap that sits on a golf ball with your initials, a symbol or your own logo cut clean through it, plus grip tabs so you can hold it steady. Drop it over the ball, run a marker through the cut-out, lift it off, and every ball gets the same mark.

How to use it

  1. Type your initials or upload an SVG logo.
  2. Check the preview: the design is projected onto a sphere, so it curves with the ball rather than sitting flat.
  3. Download and print, then use a fine permanent marker through the cut-out.

The closed-letter problem

A stencil is a hole, so the middle of a closed letter has nothing holding it in. The counter of an O, the triangle in an A, the hole in a P: cut those straight through and the centre falls out, leaving a blob instead of a letter.

The generator adds tie bars, thin bridges that hold those islands in place. They leave a small gap in the drawn line, which is exactly how every physical stencil works and is why stencil lettering looks the way it does. This is a design feature, not a defect.

Marking a clean ball

Common problems

The letters have gaps in them

Those are the tie bars, and they are deliberate. Without them the middle of a closed letter would drop out entirely. Every physical stencil works this way.

The ink bled under the edge

Too much ink, a tip that is too broad, or dragging rather than dabbing. Use a fine tip and dab straight down.

The cap does not sit properly on the ball

Golf balls are a standard diameter, so a poor fit usually means the print came out slightly undersized or has elephant's foot on the first layer. Check the first layer and reprint if the rim is squashed.

My logo lost all its detail

A stencil cut through a curved cap cannot hold very fine detail, and everything enclosed needs a tie bar. Simplify the artwork to bold shapes with clear separation.

Common questions

Why do the letters have small gaps in them?

Those are tie bars, and they are deliberate. A stencil is a hole, so the middle of a closed letter like O, A or P has nothing holding it in and would drop out. Tie bars are thin bridges that hold those islands in place, which is how every physical stencil works.

What marker should I use?

A fine-tip permanent marker. A broad or chisel tip bleeds under the stencil edge. Dab straight down rather than dragging, and let it dry before lifting the cap straight up.

Can I use my own logo?

Yes, upload an SVG. Keep it to bold shapes with clear separation: a stencil cut through a curved cap cannot hold very fine detail, and anything enclosed needs a tie bar.

Will it fit any golf ball?

Golf balls are a standard diameter, so it should. A poor fit usually means the print came out slightly undersized or has elephant's foot squashing the rim, so check the first layer.

What print settings should I use?

0.12 to 0.16 mm layers and 3 perimeters, printed rim down on the bed with tree supports (organic in PrusaSlicer) holding up the inside of the dome. The cut edge is what shapes your line, so its finish is what matters most.
