A cheap and effective means of drawing a straight line on your golf ball. This design is slightly more than half a sphere which allows the ball marker to snap over the ball to keep it from slipping when drawing the line. Openings at both ends assist in aligning the line perpendicular to the axis of the labels on the ball. The slot is slightly tapered to allow for the wide tip of a Sharpie marker.

Printed in PLA or PET with supports on the build plate only using 0.4 nozzle, 0.2 layer height, 2 perimeters and 15% infill. If you have an XL, then try the support in PLA while printing in PETG for that perfect inner surface.
