Want a modular hose boom arm for your CNC machine?
This design features a 25.4–26mm opening and is intended to fit 3/4" EMT conduit, which has an actual outside diameter of approximately 1".
Important sizing note: EMT conduit is sold by trade size, not actual outside diameter. When purchasing conduit for this design, look for 3/4" EMT conduit at your local hardware store or electrical supplier. Do not purchase 1" EMT conduit, as that refers to the trade size and will be too large.
Use this design to create custom-length boom arms for supporting PwnCNC Ultimate Hose Clamp attachments, dust hoses, wires, coolant lines, air tubing, and other CNC accessories.
