The file 'K40 Laser USB Port Fitting 3D Printer Model' is (stl) file type, size is 2.9MB.
This is a fitting for a K40 laser so that the hole that gives you access to the USB port is not so empty looking. I had to trim up the flanges and glue one of the clasps that broke with super glue. It would probably be tougher if you used flexible filament.
