My Customized Improved Phone Case

thingiverse

The code provided is a G-code for creating a phone case using a CNC machine. Here's a breakdown of what the code does: 1. Defines a series of coordinates that represent points on a grid, presumably where screws will be attached to hold the phone in place. 2. Specifies the dimensions and shape of the case: * `custom_back_extra_port_x_size`: The size of the port on the back of the case (30mm). * `custom_top_outer_edge_chamfer_radius`: The radius of the chamfer at the top edge of the case (.6mm). * `custom_corner_radius`: The radius of the corners of the case (10mm). * `custom_right_port_corner_resolution`: The resolution of the corner where the right port is located (8 steps per revolution). 3. Defines a series of settings for the CNC machine: * `stencil_pattern_element_overlap`: How much to overlap adjacent pattern elements when generating the stencil (0 steps per revolution). * `use_stencil`: Whether or not to use a stencil for creating the case design (1=on, 0=off). * `stencil_rotation`: The angle at which the stencil will be rotated when generating the case design (0 degrees). 4. Specifies various custom dimensions: * `custom_case_wall_thickness`: The thickness of the walls of the case (1.6mm). * `custom_overhang_thickness`: The thickness of the overhangs on the bottom and sides of the case (.8mm). * `pattern_element_radius`: The radius of the circular pattern elements used to generate the case design (14mm). * `custom_phone_width` and `custom_phone_thickness`: The dimensions of the phone that will be inserted into the case (100mm wide, 10mm thick). 5. Sets various options: * `use_pattern`: Whether or not to use a pattern for creating the case design (1=on, 0=off). * `use_mouse_ears`: Whether or not to add mouse ears ( small protrusions) at the top corners of the case (1=on, 0=off). The G-code then defines the sequence of operations to create the phone case. These operations include: 1. Cutting out a circular hole for the camera on the back of the case. 2. Creating the ports and slots in the case design. 3. Cutting out a slot for the top port ( microphone hole). 4. Rounding the corners of the case. The final line of the code, `; Layer: Case 00001 M42 P13 I8 L1200 C5 D9 F120 T0 G18`, instructs the CNC machine to execute this series of operations using a particular setting and tolerance (T= printer tolerance). Overall, the code creates a customized phone case with various ports and features. The `custom_*` variables can be adjusted to change the design parameters and produce different versions of the case. It's worth noting that creating such cases typically involves much more advanced procedures involving several layers, precise calculation for cutout details such as port locations and diameters (some parts being critical and need accurate execution for secure placement), ensuring accurate orientation while generating stencils which may overlap each other or surrounding materials; but in its essence, these procedures serve similar purpose as provided above code, producing an identical 3D-printed model from design blueprint provided to generate precise dimensions using mathematical formula's or parametric programming
