Alright, time for some fun!
First off, some side by side pics:
Opening the case without breaking the tabs really was as easy as opening a book. Thanks for the tips!
Removing screws of the PCB was also easy. I chose to keep the controller connected. The only annoying one was the screw below the controller connector cables.
Popping out the slider was a bit tricky at first. I thought I was supposed to pressure on the top of the slider. After a while I figured out just to press down on the bottom of the slider and it literally popped out and flew 2 meters away
Result:
Now I'm waiting for my MX VERY VERY skyblue keythulu!
Thanks again for the design Matt3o! I'm really impressed. The key press is not as smooth as the original slider at the moment so I will choose to not do my whole keyboard. However, it is great to show off novelties imo
