Here is a flat base version of the Always Rightward Pointing Arrow Illusion. I have modified the desgin to have a flat base to ensure support less printing. 4 model files are uploaded with holes of 8.1mm, 7.1mm, 6.1mm and 5.1mm diameter with depth 7mm. This model can be easily mounted on a simple pencil or a screw-driver, just choose the model with right dimenstion of hole. Orginally created by amazing Kokichi Sugihara, a Japanese mathematician.
