N54 Intake Vacuum Adapter

thingiverse

This is a vacuum adapter specifically designed for blasting the intake valves on a BMW N54 engine. Its primary objective was to be easily printable and result in a strong, durable final product. The design incorporates a swivel mechanism that helps reduce stress caused by the vacuum hose connection. I personally use this adapter with a shop vacuum featuring a 1-3/4" outlet. The necessary printed parts include: N54_Vacuum_Adapter_A N54_Vacuum_Adapter_B To assemble and complete the system, you will need to acquire the following components: A 90-degree plastic push-to-fit disposal waste elbow with a 1.5-inch diameter A flexible drain and trap connector suitable for 1-1/2" or 1-3/4" pipe sizes Four socket head cap screws measuring 8-32x1 inches in length Eight #8 washers Four #8 cap nuts
