This is a customizable phone/tablet holder.

Update: Thingiverse Customizer app friendly

Uploaded STL is for iPhone 5S

Parameters

device_dimensions

Dimensions of device (width, height and thickness)

The main parameter which defines almost all geometry.
Measure your device for best match and add some tolerance to all dimensions (0.5mm is ok).
If you use case then measure it within a case.

Examples for iPhone 5S ([58,124,8]), Huawei Nova 2 (in case) ([75,145,16]) and Samsung Galaxy Tab 2 ([238, 169, 10])

charger_dimensions

Dimensions of charger cable (width, height and thickness), include some wire in charger height

Examples for iPhone 5S ([8, 40, 5]), Huawei Nova 2 (in case) ([12, 50, 7]) and Samsung Galaxy Tab 2 ([30, 50, 8])

charger_position_factors

Since most devices has charger hole in middle of bottom - default settings must be good,
however if you have some exotic device with charger in the left or right bottom corner you must
tune this parameter.

To compute factors using direct offsets in mm

charger_position_factors = [
    offset_from_left_edge_in_mm / device_dimensions[0],
    offset_from_bottom_edge_in_mm / device_dimensions[2]];

Examples for [0.1,0.5], [0.5, 0.1] and [0.9, 1.0] offsets

front_support_height

Height of front support. Set to zero if you dont want front support at all.

Examples for 0, 5 and 15 mm

front_support_fillet

Front support fillet radius. Must be less or equal to front_support_height

Examples for 0, 5 and 15 mm

holder_thickness

Thickness of whole holder

Examples for 2, 3 and 5 mm

holder_fillet

Fillet radius for base and foot parts

Examples for 0, 10 and 20 mm

holder_angle

Angle of holder

Examples for 30, 50 and 70 degrees

holder_cut_factor

Factor to cut base.
Great filament saver, but be sure that it isn't very short - 0.5 usually a good value to stick with it

Examples for 0.0, 0.25 and 0.5

shelf_shape

Shape of shelf - possible values are "darc" (double arc), "arc" or "tri" (triangle - original variant)

Examples for "darc", "arc" and "tri"

shelf_additional_height

Additional height of shelf to allow some smoothing.
Set it to zero if you want flat shelf.
Defaults to device thickness + holder thickness

Examples for 0mm, default and 30mm

arc_radius

Radius of main holder arc - by default its computed depending on charger_dimensions[1] (i.e. height of charger),
in most cases computed value must be ok,
but if you wish to make an arc larger or smaller you can adjust this value (BUT be sure that charger cable will fit)

Examples for 5mm, default and 30mm

foot_length

Length of foot - by default its computed as projection of mounted device to the table.
In most cases computed value must be ok,
but if you wish to make foot larger or smaller you can adjust this value (BUT be sure that the holder will be stable)

Examples for 30mm, default and 100mm

pattern_outlines

Outline for pattern fills (defaults to holder_thickness).
Array with 2 values (for base and foot correspoding)

Examples for [2, 2], [5, 5] and [10, 10]

pattern_presets

Selected pattern fill presets (see below about preset indexes)
Array with 2 numeric values (for base and foot correspoding)

Patterns

Each image corresponds to preset pattern.

Example:

pattern_presets = [10, 20];

means that 10 pattern will be used for base
and 20 pattern for foot

Slicing

For best quality print - print it on the left or right side, i.e. rotate 90 or -90 degrees around the Y axis
