I was looking for a way to prevent my 4" dust collector hose from getting pinched between my X axis and Y axis rails on my Workbee CNC.  I have made two variations of this mount, one for the spacers on the nema23 stepper on Workbee or Lead CNCs and another that fits on the NEMA23 stepper itself.  Please let me know if you have any questions.  If you are interested in 3d printing one yourself, check out the blog!
