Cobra 3D Printed Grandsport 35 Putter

Mallet Putter

The Cobra 3D Printed Grandsport 35 is a 2025 mallet, and the name is the whole pitch. The head is printed from metal rather than cast or milled, which lets Cobra build an internal lattice you couldn't make any other way. Picture a web of tiny struts instead of a solid block. The lattice holds the shape and strips weight out of the middle, and that saved weight gets pushed to the perimeter where it does the most good. A putter that resists twisting on off-center strikes is a putter that keeps your speed and line honest on the misses, and that's where three-putts come from.

Up front the Grandsport 35 carries a SIK face with Descending Loft Technology, four small lofts milled into the strike area. The idea is that no matter where your hands are at impact, whether you deloft the shaft or add loft, one of those lofts launches the ball on a consistent roll. Combined with the high-MOI head, the design is built to take two of the biggest variables in putting, strike location and shaft lean at impact, and quiet them down. You still have to read the green and start it on line. The head just gives you a wider margin when you don't do either perfectly.

The number to check before you buy is the toe hang. This one has mid toe hang, meaning the face rotates a moderate amount through the stroke. That fits a player whose putter travels on a slight to moderate arc, opening back and closing through the ball. If your stroke is dead straight back and through, a face-balanced mallet is the better match and you'll fight this one. Match the hang to how you actually swing the putter and the Grandsport 35 feels like it's working with you.

Design

The 3D printed lattice is the reason this head exists. Printing the body lets Cobra hollow out the interior with a strut network that a mold or a mill can't reproduce, so mass comes out of the center and gets relocated to the heel, toe, and back. That raises MOI and keeps the face square when you catch one thin or off the toe. The SIK face insert sits in front, milled with four descending lofts so ball launch stays consistent whether you lean the shaft forward or hang back at impact. A milled aluminum section and tungsten weighting balance the feel and set the head at a stable static weight. Mid toe hang is a deliberate fit rather than a byproduct of the shape. The head is stable and forgiving, but the weighting lets the face release on a moderate arc so a player with that natural stroke gets a putter that opens and closes in time with the hands. As a mallet, the Grandsport 35 has a bigger footprint than a blade, and the alignment aid on the crown gives you a clear reference to set your start line behind the ball. The tradeoff for that size is what you'd expect. You get forgiveness and easier aiming, and you give up the compact look a blade player likes to tuck away and manipulate.

Who It's For

• Players with a slight to moderate arc stroke, since the mid toe hang matches a face that releases through impact instead of staying square.
• Golfers who miss the center of the face and pay for it in speed, because the 3D printed lattice pushes weight to the perimeter and holds the head square on mishits.
• Anyone whose shaft lean at impact varies, since the SIK descending-loft face is built to launch the ball consistently regardless of where your hands end up.
• Players moving off a blade who want more forgiveness and a clearer alignment reference without giving up feel.
• Golfers curious about 3D printed metal construction who want a real performance reason behind it, not just a novelty.

About Cobra

Cobra's 3D printed putters use additive manufacturing to create complex internal structures impossible with traditional methods, allowing precise weight placement for optimal MOI and feel.

Frequently Asked Questions

What does 3D printing actually do for the Grandsport 35?

It lets Cobra build an internal lattice inside the head that you can't cast or mill. The head prints as a web of small struts rather than a solid block, which removes weight from the center and lets Cobra move it to the perimeter. More weight around the edges means higher MOI, so the face stays square and holds its speed when you strike it off-center. The printing isn't a gimmick here, it's the only way to get the weight exactly where the design wants it.

Is the mid toe hang right for my stroke?

It depends on your arc. Mid toe hang suits a stroke that travels on a slight to moderate arc, where the face naturally opens on the way back and closes through the ball. If you putt straight back and straight through, a face-balanced mallet fits you better. To check at home, balance the shaft on your finger. If the toe droops partway toward the ground rather than pointing at the sky, it's a toe-hang putter meant for an arc stroke, which is what this is.

What is the Descending Loft face and why does it matter?

The Grandsport 35 uses a SIK face milled with four small lofts, called Descending Loft Technology. Golfers deliver the putter with different amounts of shaft lean at impact, and that changes launch. The idea is that whatever your hands do, one of those four lofts sends the ball off on a consistent roll. It's aimed at players whose impact position isn't perfectly repeatable, which is most people, and it helps steady out your distance control.

Does the Grandsport 35 have an alignment aid?

Yes. There's an alignment aid on the crown to help you set the ball on your intended start line. Paired with the larger mallet footprint and the high-MOI head, it makes this putter easier to aim and steadier through the stroke than a blade. If aiming consistently is a weak spot in your game, the sightline plus the bigger head is a real reason to look at a mallet like this one.

Will the Grandsport 35 help me stop three-putting?

It targets the two usual causes. The 3D printed high-MOI head keeps your speed more consistent on strikes you don't catch flush, so the first putt is less likely to come up short or run long. The alignment aid and mallet shape make it easier to start the ball on line. It won't read the green for you, but on speed and aim, the two things most three-putts come down to, it's built to give you more margin.
