Shapeoko 3 18x37mm Drag Chain Brackets (w/ Beaver HDZ Upgrade)
thingiverse
Having upgraded my SO3 to an SO3 XXL with Beaver's HDZ Z-Axis upgrade as well as a fat water-cooled 2.2kw spindle, I needed the biggest drag chains I can get and still have it fit under the X stepper motor on the X axis. Best one is by far the 18x37mm drag chains you can get off Amazon and eBay. I needed something big to fit not only the standard wiring, but also the BIG spindle cable (16mm+!!) as well as 2x water hoses for the spindle. The left sided bracket will fit on any standard SO3. The X-axis bracket is for Beaver's HDZ Z-axis upgrade. This thing is an amazing beast (no more lost z steps)! The left Y-axis bracket mounts with 2x M4s+nuts to the X gantry plate. The X-axis bracket attaches behind the HDZ's Z-axis plate, also with 2xM4s (30-35mm). Use the included 22mm spacers as pictured.
