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

thingiverse

<b>Acknowledgements:</b> This item is totally inspired by the splendid efforts of MXRR (see box on the left). Those items worked perfectly well - but I have big fat fingers and found them very fiddly! <b>Design:</b> I modified the OpenSCAD code for my M3 nut screw heads (https://www.thingiverse.com/thing:2530144), 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). <b>Note:</b> 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 <i>chamfer.scad</i> for convenience. <b>08/02/2022 - LATE UPDATE!</b> When I put these on my Sculpfun S9 I found that the top of the knob barely cleared the X-axis driveshaft - I have reduced the height by 1mm to give a little extra clearance.
