I was just super tired of the top buttons on my Joycons being completely different than my painted shell so when I bought myself some new clear shells to paint more properly I absolutely had to remake the SL and SR buttons.

These are STUPID basic and are missing the letters and also the little tabs that denote which lettered button goes in which slot cause all those are for is to denote which hole which goes into. I feel like if you can't work out which button is which normally then maybe you shouldn't be modifying your Joycons? LOL!

Anyway my recommendations when printing this... I went with:

Nozzle size: 0.4mm
Layer height: 0.1mm
Supports: Yes probably?
Adhesion: Skirt

IMPORTANT
Your first layer squash is going to make or break this part! If you are too close the scale of the parts that actually push things is going to be WAY off and make the button not work properly! I also do not recommend rafting this part since it's so small. Unless you are very good at adjusting your raft air gap!

I'm recommending supports when printing in default orientation with the caution of there being a small stick inside the button to depress the actual button on the board inside the Joycon. This stick is PURPOSEFULLY A TINY AMOUNT SHORTER THAN THE OUTER PART OF THE BUTTON! If this stick is extended it will not function properly! To get around this little bit of weirdness which is a 3D printing only problem either print it upsidedown with the hole up (though this will mess with the look of the top of the button and may make it so you have to trim it some and/or the button will straight up be too short to push properly depending on how hard your squash is) or print it regular hole down with support but you will have to ensure you remove the small bit of support under the stick!

I REPEAT THE STICK HAS TO BE ABOUT 1MM SHORTER THAN THE OUTSIDE OF THE BUTTON!

That is all...
