You can order covers from Aki Asahi, Cameraleather, or Hugo Studios. Much easier than developing your own file, figuring out how to attach, etc. Also if you are using a laser to cut, many camera skin materials will be toxic in burning.
Anyway, I do have a vector file for an LM model. This will give you the overall outside shape and spool knob locations Then you'll need to remove and redraw some of the interior cuts. It's in Illustrator format so you'll need to convert as needed. they won't let me upload the file here so drop me a PM and an email to send it to.
