The design is easy to print, you do not need any additional tools. You can print everything in one material. I designed it in terms of PETG, printing with ABS the handle will not work because this material has a different level of shrinkage, keep this in mind.

IMPORTANT! In order for the whole structure to work properly, the airflow control bar must be removed, as in the version with an automatic holder. At first I thought it could be done without interference, but the reality was different, the handle would have to be gently angled to fit, and I wanted to maintain the standard of the cup hole.
