The start of school is approaching, so the fun of learning should not be missing. This table calculator is a wonderful gift for all children who still want to learn or need to consolidate the little 1x1. I think the sliders and the assembly are self-explanatory. I recommend the print profile to everyone, but if necessary the individual files are also available. It was printed with PLA, nozzle 0.4 at a layer height of 0.2.
