I've created a little container to carry up to 4 ND Filters from the Runcam Thumb Pro 4K (new Wide edition). Additionally there are 6 slots for MicroSD Cards. The lid is thread based and takes about 2x 360° turns to open it. Support could be added to the thread, but I've printed it without and it works fine.

I've set the plate type to print by object so people without an AMS just have to add a pause at Layer 71 if they want different colors for the bottom and the lid like i did.
