For those that like to keep everything in one case, I posted these options a while back…
It fits well in a Pelican 1170 case, or as you see here, a knockoff Meijia case from Amazon for half the price.
and …
It turns out that an A5 binder is the perfect size, so I designed an insert to clip into the rings and hold everything together. Anyone can download and print the .stl file or send it to your favorite online print service, then pop it into any old(or new) binder. I also added a split version (1a & 1b) for people like myself with small printers(you can see the seam in the pics). It’s up on the github in the hardware folder - GitHub - PocketMidi/KB1: A pocket size midi keyboard controller with speakers for the Polyend Tracker Mini (2023).
Here’s the .stl file
A5 frame.stl.zip (442.2 KB)
There’s also plenty of padded book sleeves and bags on amazon, but I haven’t tried too many.
If anyone has any more suggestions, please post it here.
