I printed this for my kid in PLA, but I did not want to mess with supports on this simple, yet fairly large print. So, I made simple mods to original STLs in Tincercad with some 45 degree shapes to print without supports. Mirrored and modified STL is also provided.
Printed with 20% infill, transparent PLA.
