I built a custom stick out of 3mm MDF and a 2mm thick acrylic panel.
It measures roughly the same in both width and length as a TKL keyboard.
The stick is light but doesn’t move around on my lap, (where I use it from).
Only thing I messed up a little is drilling the acrylic, which you can see slightly under some buttons.
I just wanted to leave this here because virtually all of the posts online suggest much sturdier/thicker builds and, in my experience so far, this works just fine if you are not a complete savage
Hopefully this will encourage people who may not have so many tools to build lighter but still usable sticks.
On a completely unrelated note, I noticed that your stick has Ryu as artwork, but the 3 move-names listed are the Hadoken, Shoryuken, and the Tatsumaki Zankukyaku; the latter which is Gouki/Akuma’s Hurricane Kick rather than Ryu/Ken’s. Was that intentional?
Not at all, I noticed the same after finishing and double checking with google translate, but didn’t think it was worth the effort to print it again, take everything off, etc, it looked cool enough to me and I kept it as a reminder that life itself is flawed all the time
