Or print what you want. I aint your boss, follow your heart! Note that the pre cut track pieces are hollowed out, while the full modell still has a solid track spine. All the pre cut parts either have pins or holes in order to be plug and play. Depending on your printers tolerances you might need to sand these down, or fill in the gaps with some simple paper inserts. Alternatively you can cut the modell yourself and glue it together. On the cut parts the pins in the rails are very fragile and will most likely break out, this is fixed on my newer models.
