My son loves to play Fortnite aggressively so he broke the spacebar on his Razer Cynosa Chroma keyboard.
I tried to replicate the same spacebar but I couldn't get the details to print right. So I've come up with a different solution. It turned out to be sturdier and much more resilient to aggressive playing :P
I've included two different surfaces for the spacebar, one with a spine and the other is flat. You can also have two types of pins, one is a rod and the other is a pin type inserted from both ends. I recommend gluing the ends or tape the ends for the bar.
Printed on Creality Ender 3 default setting with PLA. The support was a bit challenging to remove, but on a slower print, it printed the support with care. So it was easier to remove. I'm thinking of spray painting it for a better-finished look.
