📄️ Making The Stem
From here, the story changes. Cherry switches have a plus-shaped stem that's 4mm long and 1.17mm wide, but other brands of switches have their own dimensions. It's up to you to do research on the dimensions!
📄️ Customization
You have a nice looking custom keycap, but to make it truly custom and ✩ polished ✩, you have to add some flair to it! This can range from adding some fillets and text to the top, to adding completely new models to the keycap or changing the entire shape of it!
📄️ Changing the shape of the cap
To change the shape of the keycap, you can go into Fusion's timeline, a bar on the bottom of the screen containing command icons like Extrude or Fillet that shows the history of your model. From here, you can change many things about the keycap!
