Fixing screw add-on heads for the Sculpfun S6/S9 laser unit, in OpenSCAD

Acknowledgements: This item is totally inspired by the splendid efforts of MXRR (on Thingiverse). Those items worked perfectly well - but I have big fat fingers and found them very fiddly! Design: I modified the OpenSCAD code for my M3 nut screw heads (https://cults3d.com/en/3d-model/tool/m3-screw-knob), enlarging it a bit and adding a cavity for the Sculpfun fixing screws. At the moment they seem to work well - I have yet to prove whether they will get in the way on very large jobs, at the limits of the Y axis (not expected). Note: If you want to play with the OpenSCAD code then you will have to download the library from ThingiVerse (https://www.thingiverse.com/thing:1305888). I renamed this library file to chamfer.scad for convenience. Minor update: I found that these add-on heads only just cleared the X-axis drive shaft when fitted - I have reduced the height by 1mm to allow a little more clearance.
