A message in a bottle for the ball stuck in the gorse, the bunker or the car park. SEND over HELP, two four-character lines in big letters. The only closed shapes are the D and the P, which keep their middles on thin stencil bridges, so it is one of the simplest caps in the set to print and to fill.

Made with our free golf ball stencil generator, not modelled by hand: we typed SEND / HELP into its Initials field on two lines, chose the Bold & Blocky font and set Size to 30 mm. Everything else is the tool's default, and the STL in the zip is exactly what the tool gives you: a 71 by 48 mm cap for a standard 42.67 mm ball, with a 2.4 mm wall, 0.5 mm of clearance, a skirt that reaches 12 degrees past the middle of the ball so it cups it, and two tabs with 7 mm holes for a rubber band. Like every free download from the tool, it carries a small raised MESHCAST mark on its underside, along one tab.

Seat it on the ball, draw through the openings with a fine permanent marker, lift it off, and the joke is on the ball in under a minute. It makes a cheap, quick gift for a golfer: print the cap, mark a sleeve of balls, hand over both.

What you need

4
  • A standard golf ball, 42.67 mm
  • A fine permanent marker (the letters are small, a chisel tip is too broad)
  • About 15 g of PLA or PETG
  • A rubber band, if you want to hold the cap on through the tab holes

How to make it

5

  1. Print the file as exported: rim flat on the bed, dome up, with tree supports on (organic in PrusaSlicer).

  2. Peel the supports out of the inside of the dome.

  3. Wipe the ball clean so the ink bites, then seat the cap on top and press the rim down until it cups the ball.

  4. Draw through each opening with short strokes from the edges inwards.

  5. Lift the cap straight up and leave the ink for a minute before you touch it.

Questions about this design

Will anyone actually read the SEND HELP golf ball stencil mark?

Anyone who picks the ball up will: the letters are big and bold, clear from a step away. Whether they send help or just keep a free ball is up to them. It works best as a gift for the golfer who spends more time looking for balls than hitting them.

How do I print the SEND HELP golf ball stencil?

Print it as exported, rim flat on the bed and the dome up, with tree supports switched on (organic in PrusaSlicer, tree in Bambu Studio, Orca and Cura). They hold up the inside of the dome and peel out easily. At 0.2 mm layers and MK3-class speeds it takes about 1 h 20 min and 15 g of PLA (estimated from the file, not sliced); a current printer is faster.

Can I change the words on the SEND HELP golf ball stencil?

Yes. Open the free golf ball stencil generator, choose Initials and type your own words, up to two lines of six characters, and pick the Bold & Blocky font to match this one. The Ball size, Clearance and Size sliders fit a different ball or change the mark; this one uses a Size of 30 mm.
