Otherwise adjusting the extrusion width slightly (+/-.05) can fool S3D into getting a better thin wall fill. Working on this right now! ๐Ÿ˜ƒ I redesigned the box so that all of the walls are a multiple of 3 of the default extrusion width (.6mm). So all the walls are now .070866" thick. The gcode preview looks promising. Iโ€™m printing right now! ๐Ÿ˜ƒ ---

I just wanted to thank you guys for the info youโ€™ve shared. I was having trouble with a part I was trying to print, and some of the changes in S3D you discussed helped me solve the problems. ---

Great, glad you were able to get something from it! Coincidentally, I just printed a GoPro item Iโ€™m designing and am having the same thin wall gap problem now. Go figure! [Previous page](https://forum.lulzbot.com/t/solved-abs-print-issue-blobs-zits-on-final-print-pics/4025.md?page=1)
