If you are using a hose boom and are looking for an effective way to secure the hose with a diameter of 57mm to the X gantry then this is for you. I am running a spindle and this cable chain system: https://www.thingiverse.com/thing:4619804 with this hose: https://www.homedepot.com/p/RIDGID-1-7-8-in-x-10-ft-Pro-Grade-Locking-Vacuum-Hose-Kit-for-RIDGID-Wet-Dry-Shop-Vacuums-LA2570/305626336. This requires the hose to be offset to the side of the Z axis motor. If using this with the cable chain system this mounts using two M6 x 25 allen head bolts.
