Do It Yourself, 3D-Print, IP64 Waterproof Case for generic Smartphone

An OpenSCAD model of a smartphone case, suitable for motorbike mounting and GPS navigation.

• Main body and front frame made with 3d-printed nylon; allow GPS signal reception.
• Aluminium back panel (laser cut) and silicone padding for heat dissipation; should operate under summer direct sunlight.
• The screen is protected by a PETG sheet (laser cut).
• At least IP64 protection: dust proof and water splashing from any directions.
• Customizable for any smartphone, just input the measures and 3D-print it!
• Passthrough hole for power cable.
• Operating smartphone side buttons.

NOTICE: This project is still in beta stage, the object was not actually build yet.

The OpenSCAD model

Parametric Project

You should set at least the size of your device (smartphone) and the position of the side buttons (at the moment only le right side is coded). Browse the ip64-smartphone-case.scad and search for phone_x, phone_y, phone_z variables. Buttons coordinates are into btn_right_pos_y array.

Exploded View

Open the proj-assembling-test.scad file and see the preview. To see an exploded view, set the exploded variable to a value greather than zero (it is millimters, try with 20).

2D print test

Open the proj-2d-test.scad project file, render it and export in DXF format. It is a 2D drawing that you can print on paper, so you can check the overall dimensions and actual smartphone fitting.

3D Printed parts

For 3D printing you must render two objects:

• Main body.
• Front frame.

Use the file proj-3d-print.scad to lay-out the object for the manufacturing. Before starting the final rendering, set proper values for the variables rounded_fn and smalld_fn. They control the $fn OpenSCAD special variable, i.e. the number of fragments to render a full circle. The first variable is for rounded objects, the second is for small diamters pins and holes. You should try rounded_fn=92 and smalld_fn=64 at least.

Laser cut parts

• Aluminium back panel.
• PETG screen cover sheet.

Miscellaneus parts to be purchased separately

• O-Rings for clevis pins.
• O-Rings for power cable grommet.
• O-Ring cord for main body seal.
• Nuts and bolts for main body assembly.
• Thermally conductive silicone rubber.
