Sony Xperia 10 IV bumper case

UPDATE 2023-04-07: Added a case with a slot for a wireless charging receiver. Also hides the connector so less chance of it snagging on something and ruining your usb port. I measured roughly 400mA charging current so beware it is very slow, but if you have time it'll be better for your battery.

DISCLAIMER: This case is mainly to try to increase friction when holding the phone, not to protect from falls.

case = My “final” version of the case with all the holes, chamfers and features made to be printed with stiffer materials like PLA and PETG. Experiment in slicer with 6-10 walls and 0 bottom layers to get nice infill backing.

case thin back = Same as above but with a slightly thinner back. 1.75 → 1.2 mm

case TPU = Same as “case” but without the slits in the corners. 92A hardness is too floppy but prints ok, haven't tested with harder TPU. Might also have to scale down slightly.

case smooth = Without the grip texture on the sides.

case base = Just holes without any chafers or fillets.

STEP file included for remixes.
