Following on from the discussion in this thread https://forum.bambulab.com/t/realistic-rendering-of-fdm-3d-prints-in-fusion-360/96012
As requested by @SithJedi and @Goldjunge491 I have uploaded a version of my addin - which is an enhancement of an earlier work by K Nunley to GitHub as a fork against his original addin here.
NB/ I am a bit of a novice with Github - so the way I have uploaded it may need to be improved.
