I was having trouble finding the line lasers izytronic called out (and frankly the duct tape shim bothered me) so I modified this version to fit diodes that are easy to find in the USA. I also switched to chamfers instead of radius edges for a cleaner print and unified the alignment. A version for the 2.8W laser bundle is here: http://www.thingiverse.com/thing:1025450References: If the fit is too tight remove the warning label from the line lasers (you wouldn't have been able to read them anyway) and stick them wherever you think they look best on the outside shell.
