This 4 speed gearbox can be used as an example for the "Spice for Mechanical Engineering PAM". You need to print: - 1 x "Festrad 1-4" - 1 x "Losrad 1-4" - 4 x "Schaltklaue" You need to bond two "Schaltklauen" back to back to get a functional part. The adhesive which I would recommend is "Uhu Hart Kunststoff". To ensure that both parts are well alligned, use an axle to align both parts during the adhesive cures. I addition you will need: - 2 x lego techic axle 10L - 15 stopper small If you print each "Schaltklaue", "Festrad" and "Losrad" in a different color, it is very helpful to indentify in which state the gearbox is. Printing paramters: - Printer Spark Cube V1 - PLA - nozzle diameter of 0.4 mm - Layerheight 0.25 mm - 15% infill - no support
