A single piece 3d printed version of a Cranmer abacus. This abacus can be fitted with pipe cleaners as the rods and 8 mm inexpensive wooden beads with an outer diameter of 8.0 mm and inner diameter of 2.4 mm.
The print takes 4.5 hours at .24 layer height, 30% infill, and 75 mm/sec print speed. There are no supports or bed adhesion necessary.
Thank you to Kanay for inspiring the original tiny abacus I created for Mountain Lakes Math Day.
Thank you Monique Coleman for explaining the practical needs of a student's abacus. I look forward to you and your student's feedback. Please share design and print feedback!
Version #2 Highlights
1 - Abacus counters are now rounded cubes (instead of semi-spheres)
2 - There is an abacus backing, allowing you to paste on contrasting color paper or felt backgrounds.
3 - A one piece 3d print! Pipe cleaners act as rods, which is inexpensive, color customizable, and provides a way to naturally keep counter beads in place
4 - Wooden c
