In this thread I will share my process of designing and printing g shock ga 100 casings/bezels. I have been having so much fun, and there is so much potential for members to design their own parts.
I begin the process by measuring all critical dimensions of the physical part using electronic calipers. This includes the inside and outside diameters, depth, hole patterns, etc. The idea is to gather as many measurements as possible and take the average values!
Next, I use the data to start designing the part in CAD. Here, I am using Autodesk Inventor. I start by creating a simple extrusion using the inside and outside diameters.
I add the detailed features of the casing using circular patterns and extruded cuts. No functionality really, just looks and aesthetics. Inventor allows you to do many custom features like engravings and embosses.
Here, I am sketching the extrusion for the where the wristband connects to the g shock module.
I add a couple more key features like the hole pattern for the screws, and the button features. Getting the screw locations right can be tricky , especially on the first try. Take your time to get accurate measurements and double check.
I upload the stl file to a third party 3d printing service. the software checks for wall thickness issues, depending on the material requested. Make sure all features are within tolerance for solid wall thickness

The final result :)
