A printed cap that marks a duck over HOOK on a golf ball. The duck hook, the shot that dives left and never comes back.
A picture puzzle for the shot that starts left and dives lower: a rubber duck over the word HOOK, so the ball reads DUCK HOOK. The duck is a round, friendly silhouette with a beak and a tail; its eye is a small island tied on with a thin stencil bridge, as are the middles of the two Os.
Made with our free golf ball stencil generator, not modelled by hand: we drew a duck over HOOK as an SVG, the word set in the tool's own Bold & Blocky outlines, chose Upload under Design from, loaded the file and set Size to 32 mm (the SVG is in the zip). 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.
Shown as a 3D render of the printed stencil on a golf ball and a second ball with the words drawn through it, not a photo.

Print the file as exported: rim flat on the bed, dome up, with tree supports on (organic in PrusaSlicer).
Peel the supports out of the inside of the dome.
Wipe the ball clean so the ink bites, then seat the cap on top and press the rim down until it cups the ball.
Draw through each opening with short strokes from the edges inwards.
Lift the cap straight up and leave the ink for a minute before you touch it.

A duck hook is a shot that curves hard left for a right-handed golfer and dives out of the air, like a duck coming in to land on a pond. Drawing the duck instead of writing DUCK makes it a picture puzzle, and a lot easier to spot on the ball.
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 14 g of PLA (estimated from the file, not sliced); a current printer is faster.
Yes. The zip carries the artwork as an SVG of plain outlines: change the word or the picture in any vector editor, then open the free golf ball stencil generator, choose Upload and load your file. It cuts whatever you draw and ties any loose middle back on with a bridge; this one uses a Size of 32 mm.
