Among the many ideas I have already thrown out, and that other people have posted, I still think that the best second non-conductive material to extrude is fiberglass. ABS plastic is very good, but...
View ArticleUse plastruder to secure wire? (no replies)
Have you considered combining the standard plastruder with a SpoolHead tool? That is, mounting the SpoolHead tool at an angle and pointing it at the plastruder nozzle such that the wire came out at...
