FoneBlasta - Passive Amplifier for Huawei P20 & P30 Pro's (Inc full covers on phone)

thingiverse

This is a simple (but very effective) passive amplifier designed to fit Huawei P20Pro & P30Pro phones, including their covers (inc 360 magnetic covers). The phone 'slot' is 81.5mm wide, fits a phone up to 11.5mm deep and the phone sits in a recess 17mm deep and will fit many other phones. However, the two holes connecting the slot to the 'speaker' are specifically positioned to match the speakers on the named phones. UPDATE: I have uploaded a newer version called FoneBlasta! It is shorter (but no less loud!) - and so uses less filament and takes about an hour off the printing time! It COULD look more curvy etc, but it is fit for purpose and works very well. It needed tree supports where the phone fits, but everywhere else was fine. The one in the photos was printed on a FlashForge Finder, but should be fine on any printer. Standard settings were used.
