PS4 controller lazy thumb

thingiverse

Well, my old PS4 controller stick rubber had finally worn out and it was time for an upgrade. I designed a new analog stick extension that's as large as possible to give me a really comfortable feel. The bottom part of the extension is 3D printed, held together by a single 2.2mm diameter screw - no glue needed here. The top part is made from two-component molding silicone, but you can use any similar rubber or silicone substance instead. The mold consists of two parts that snap together to form the whole thing. You might need to drill a hole in the top so you can pour the silicone in. Alternatively, you can fill each part separately and then squeeze them together. Just be careful not to get any air bubbles when pouring. The design is still a work in progress, but I've already made some test prints. If you have any suggestions or ideas, let me know!
