This part is mainly used for alignment and space savings. It was designed with standard sizes of hoses, > 6mm diameter, to align wires and Pitot-tube hoses inside the fuselage and have more spaces for the batteries and other components. It can be used directly with glue/or adhesive tapes on the backside for attachments. See the photos of an RC airplane and how the Pitot-tube hoses were aligned as a result of using this part. You can print multiple ones depending on your applications. This part was designed for the University Sains Malaysia UAV project.
