About this 3D model

Printed from PLA on a Bambulab X1C printer. I recommend printing 0.2 layer. All supports. The model uses the maximum space in the x-axis(25.6cm). To print the model, you must have a bed with a size of at least 25.6 cm, that is, all bambulab except A1 mini. That is why you need to have a properly cleaned mat and preferably apply 3Dlac or stick glue so that the model does not come off. I also recommend raising the temperature of the bed to at least 50C. After adding it to the bed, you must not move the object, otherwise you will not be able to place it or print it!!!! EDIT: Fixed a bug in the geometry of the model at the beginning of the track, which caused the guide track to break. Added rounding of track ends.
