I have only found ATA style road cases that were even close to the right size. I have a lot of outdated networking and computer equipment and have resorted to using some of those enclosures for this. The next one is steel , but will be powder coated flat black in and out after all the holes and mounting plates are made. It is in hand so I am going to try it. It is 17.5" x 12" x 5". It will fit good inside my travel case too. The laser setup will be mounted on a 1/2" aluminum plate with all the optics to prevent any alignment issues. Still searching for that perfect enclosure.............It would seem that an electronics supplier would have something but I have not found it.
