A desktop abacus with ten rods and 100 beads for learning to count, add and subtract up to 100. Each row has five bicone beads and five barrel beads, so groups of five can be seen and felt by touch, with no need for different colours. The 5 mm octagonal rods press into the frame with no glue, and two slide-on feet keep it upright. Size is 218 x 90 x 221 mm. It has 113 parts: frame, 10 rods, 50 + 50 beads and 2 feet, all printed without supports (PETG or PLA, 0.2 mm; beads take two plates). Nothing to buy.
