In my part of the world Blocker 8 inch (205*130*33 mm) organizers for small hobby parts are widely available at discount stores like FixPrice and similar.

I designed inserts which turn such organizers into a neat storage for stock and aftermarket hotends and nozzles for Flashforge Adventurer 5M (Pro) 3D printers.

Only right-hand inserts are available as printable and editable STEP files. To print the left-hand versions of these files/parts, you will want to mirror the right-hand versions accordingly in your slicer. In the also included Flashforge 3MF file, mirrored parts are already provided.

Since not all printers can precizely print M6*1mm threads, you may want to improve the printed threads in the nozzle holder inserts by running an M6-1mm-sized thread-cutting tap through these holes before you screw your spare aftermarket nozzles into them.

P.S. A photo of the original organizer product sticker is included.
Enjoy.
