I found a working didgeridoo from user cam72cam on Thingiverse and edited it so that it can be printed in one.

Despite the connectors, it is recommended to glue the didgeridoo, preferably with a hot glue gun.

For beginners this is the possibility to learn didgeridoo without spending a lot of money for a professional didgeridoo.
