Joy-Con Button Guards
thingiverse
People frequently end up hitting the screenshot and home buttons on my Joy-Cons by accident. This is especially true when playing party games using single Joy-Cons. To avoid this problem, you can create custom guards for your Joy-Con buttons. These are two simple rings that can be stuck to your Joy-Cons using any adhesive of choice. You can print these guards with minimal effort. If you experience adhesion issues, use a brim to help the material stick better. I wouldn't recommend using a raft, as it can interfere with adhesion.
