Ah yes, this makes sense! Thank you very much! I already supposed to be like that, but was a little irritated, as you have other colors of the caps on the pic of this beautiful black case on the stl download page. I have just two blue, two green and one white and one red button.

thanks a lot!

Waiting for the adafruit delivery now - they will take their shipping time from US, I guess.

3D print is ready to be instructed.

all the best!

Alf

PS: One more thing - as I saw, you have added air openings on the top - does that fit the needs of the cooling of a 3b+ under intense usage? Cause these guys tend to get a little warm with time, which result in annoying throttle.

I had a variety of colors of extra caps so I used the color combination that worked for me. You can buy them cheap as they are standard 12mm tact caps but of course it is not necessary if your ok with the colors the game hat comes with.

I just used a copper heat sink and it hasn’t been an issue. The glass transition temperature of petg is around 100 C. I made mine out of PLA which has a lower glass transition temperature and haven’t had any problems.

I will go with greentec, which is based on lignine, guaranteed up to 115 degrees C, based on producer classification. Beneath that temps, the chip on the raspberry will already start to go up in flames :D

greetings,
Alf

PS: The color combination of your case is just classy, very beautiful, compliments!

@hoolyhoo thanks for confirming. I will be getting the psp mini thumb stick and try to get it working. Will post it once it's done. I plan to

1) remove left speaker
2) remove tall stick

3) add breakout board for mini stick at speaker position, get the interfacing done.
4) put 4 tactile button with 3d printed dpad on top. This will be at current analog stick position

jiofi.local.html tplinklogin is it down
I will be using double sided foam tape for mounting.
thanks broo !!

Hello,
I bought the amazing WaveShare GameHat 3D Printable Case STL's made by HoolyHoo.
I replaced the buttons by soft silicone buttons from Adafruit but the A button doesn't work anymore.
On the second picture, we can see a fragment of copper that was ripped off when I removed the original buttons.

How did you remove these buttons ?
There was some glue under the buttons and I had to tear off with a plier even after having desoldered them.
Was it the same for you ?
Thanks

Scrape the trace I highlighted in orange and solder to the exposed copper which I circled in red. The green is a GND point so just one pin is fine and don't worry about the right side that is missing pads but be sure to scrape the trace as I said above.
