I picked up a bunch of these laptop/tablet stands from Amazon recently. They're one of those products you can find under many names at varying prices but they all seem to be made of an aluminum alloy and come in multiple colors. They're collapsible and come in a nice little bag. My Digitakt and Octatrack have migrated from their upright plastic stands to these.
If you're interested then look up "collapsible laptop stand" and just look for the cheapest one that's like $12
