Flexible hours: YES

3D printing services as a side hustle are generally flexible, allowing you to set your own schedule. Many people on Reddit and YouTube mention that you can work around your availability, especially if you're handling orders through platforms like Etsy or personal websites. However, some users note that client demands can occasionally require quick turnarounds, which might limit flexibility. Hidden time commitments often include maintenance of the printer and post-processing of prints. Online communities frequently discuss the importance of time management to balance this side hustle with other responsibilities. Overall, while marketed as flexible, the reality can vary based on client expectations and the complexity of projects.
