Volvo XC70 / V70 / S60 P2 phone replacement

you will need two m3 bolts with nuts 

Replaces the factory Autoliv phone keypad module in the center stack of Volvo P2 cars (XC70 2003-2004 verified, part number 30657804). The old module is dead weight in every one of these cars now, and pulling it out leaves a hole in the center stack. This fills the hole with something useful: a 17 mm ball mount for a phone cradle and a deep storage pocket.

It clips into the same place the original did. No screws, no brackets, no cutting. The face panel copies the outline of the original, including the taper down the one side and the single rounded corner, so the gap around it is the factory gap.

Two printed parts:

- The panel with the body and the pocket. Goes into the dash and holds itself with two sprung latches, copies of the factory ones.

- The ball. Bolts to the panel with two M3 screws from the inside, so nothing shows on the outside except the ball.

What you get:

- 17 mm ball for a phone cradle, standing 24 mm off the face, in the middle of the panel.

- Storage pocket, opening 39.5 x 48.7 mm, 70 mm deep. Cards, coins, a key, a pack of gum.

- The latches are the reason this holds. Each one sits on a sprung tongue cut into the wall, the wedge stands 1.9 mm proud, and the tips are 117 mm apart. Push it in until both click.

Dimensions were taken from the original module with calipers and a traced outline, then confirmed by a test print of the panel and the latches in the car. It went in like the factory part.

Files:

- volvo_phone_module_v4.stl: the panel with pocket, one piece, 80 x 137.4 x 80 mm, about 121 g.

- volvo_phone_ball_17.stl: the ball, 30 x 30 x 32.5 mm, about 11 g.

Hardware: two M3 x 12 screws with a cylinder head and two M3 nuts. Nothing else.

Material: PETG or ASA. Do not use PLA for the final part, a dash gets hot enough in summer to deform it. PLA is fine for a fit test.

Print orientation and supports:

- Panel: face down on the plate. No supports anywhere. The pocket ceiling is closed on all four sides, so it prints as a 42 mm bridge, and the only other overhangs are 2 mm ledges under the latches. No brim, the first layer is huge.

- Ball: base down. No supports. The stem meets the sphere exactly where its surface runs at 45 degrees, and the nut pockets open upward.

Suggested settings: 0.3 mm layers, 20-25 percent infill, 4 top / 4 bottom layers, elephant foot compensation 0.15. The face of the panel is the first layer, so the plate decides its texture: a textured PEI sheet gives a matte finish close to the original trim, a smooth sheet gives gloss. Print the ball at 0.16-0.2 mm and 50 percent or more infill, it gets clamped in the cradle.

Assembly, before the part goes in the car:

1. Drop an M3 nut into each hex pocket on the front of the ball base.

2. Hold the base against the panel and run the two M3 x 12 screws in from the inside of the body. Do not use anything longer than 13 mm, it will come out the front of the base.

Installation:

1. Pull the original module out. It is held by two spring latches, one above and one below, 55 mm behind the face.

2. Push the new part straight in until both latches click. That is all.

Remix notes: the ball is a separate part on a simple interface, two M3 screws 20 mm apart on a 30 x 30 base. If your cradle wants a different ball, or a MagSafe puck, or an arm, build your own base on that pattern and the panel stays as it is.
