A quick mention that I tweaked the attachment settings on the forum phpBB software to allow...
.stl attachments as downloadable files
.gcode as Plain Text
As a general warning, the forum software doesn't virus scan these documents and files prior to posting (like the old BBS software packages of the 90's did. Did I just show my age?)
I've made this available as a convenience but I would err on the side of caution to always have anti-virus software running and scan before use
