The salesdrone at the dealer won't know. He may say yes, if he does, probe for the type and grade of plastic so you can get some welding rod and a heat gun. The National Office probably won't know, but they could get you in touch with the designer/engineer that sepc'd the plastic - they'd definitely know. Except then they wouldn't be able to sell you another $600 case to replace the one you broke. But all that aside, if you're going to try and repair it, don't use a soldering iron; it isn't the right tool for the job. Plastic welding is done with a high temperature hot air gun equipped with a fine nozzle and a rod of filler material of the same type you're trying to weld. Go to McMaster-carr and search through their plastics selection until you find one that matches what you've got, thats your best bet. Good luck.
