About this model

Could not find a decent one. All of the ones you can buy seem like 17mm and have a sloppy fit. This is true 18mm and M10 x 1.25. I printed it with PA12 CF. Screwed into the knob snug like you want it to be. On the M10 end I ran a tap for the first couple of threads so it would start easily.
