This is a mount for the inexpensive but surprisingly good banggood laser module LA03-3500 to be mounted to an Inventables X-Carve. It can be purchased at https://www.banggood.com/450nm-3500mW-3_5W-Blue-Laser-Module-With-TTL-Modulation-for-DIY-Laser-Cutter-Engraver-p-1103261.html
This mount may be compatible with other laser modules that are 40mm square with the first set of cooling fins being 7mm from the back of the module. Let me know if you have any problems with the design.
