In the present study, plastic geoboards and accessories were created as geometry teaching tools for visually-impaired students, using 3D printing. Lines, shapes, and angles were illustrated by stretching rubber bands around rivet heads on a geoboard with square edge of 10 x 10 grid array and circular edge of 4-quadrant graph. The coordinate points of 2D geometry were explored by blind touch on braille scales and raised grid lines, while z-axis pillars were used for 3D geometry by connecting rubber bands to the plane. The experimental group revealed significantly more learning achievement than did the control group, and all participants agreed that the new geoboards enhanced the mental imagery and understanding of geometry.
