Heat output is around 10w in the worst case scenario.\u003cbr\u003eCells overheat at maximum charging power even with holes, black material color and passive airflow.\u003c\/p\u003e\u003cp\u003ePETG or ABS\/PC recommended.

Port holes can be left without them.\u003cbr\u003eAlternative is using \"Make Overhang Printable\" in Cura. Alleviates the need of scraping off supports, but in the end it's less comfortable to use.\u003c\/p\u003e\u003cp\u003eIt's a function-driven design, eh. Gotta stop somewhere.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eJust search \"100w pd power bank module\" on AliExpress.
