After printing the original design, it turned out that there was one thing that did not fit my Dremel 4000 with the Dremel 225 flexible shaft. The guide for the flexible shaft had the wrong thread. It was mentioned by the author, but I didn't read the description carefully. In this remix, only this thread has been modified. Dremel appears to be using a UNF 1/2-20 thread here. I increased this thread diameter slightly for a better fit.
