How it works

Four steps to a straight line

  1. Drop in the ball

    Sit your ball in one half of the marker.

  2. Snap it shut

    Put the other half on top. The magnets pull it tight so the ball can't spin.

  3. Run your pen round

    Trace the slot with a fine marker pen to draw the line all the way round.

  4. Line up and putt

    Pull the halves apart and use the line to aim.

About Percy

Hi, I'm Percy and I love 3D printing.

I'm 8 years old and I design golf accessories with my dad. We test every version on real golf balls until it fits just right. The Ball Line Marker took us more than a dozen versions to get perfect.

Every order is printed, checked and packed by us. Thank you for supporting a young maker.
