I think i have an adequate storing and transport solution for the organelle-M
Found it on Aliexpress (https://www.aliexpress.com/item/32902826401.html). There are a couple of similar cases. Some labelled as “flute case” others as “tool case”. The fit is almost too perfect. It slides in and does not move, but there is no room for additional foam for protection.
Thought some of you might want to know.
