Prusa i3 JTech Laser Mount

A simple mount for a J Tech Photonics laser diode (https://jtechphotonics.com) on a generic Prusa i3-style X axis. Designed for a Rework-style X carriage (with four M4 screws), you need to unscrew your hotend/extruder and attach this mount to use the laser. (Any all-in-one solutions I tried limited the workable area of the laser and/or the printer, so until I get around to designing a quick-change X axis, this will have to do!) There's a little gubbin for engaging the X axis endstop, and the positioning of the laser should give it a safe clearance from the bed, but close enough to focus the laser using the Z axis of your printer.

If you need to tweak the dimensions (such as for the X endstop nub), the OpenSCAD file has all of the dimensions broken out as parameters, adjust them as necessary.
