12-18mm barrel type sensor holder, for JG Aurora A3S/A5. The holder is tested in A3S. To use this holder, I needed to remove the X-axis cover. I also used two M3x16 machine screws to replace the original screws.
The threaded version of 12mm and 18mm are added. They should be printed at 102%~105% scale depending on the shrinkage of your material. I use 102% to get a snug fit with PLA.
