1/4 NPT to OS 50 Oil Injector Prototype
thingiverse
This is an astoundingly precise part. It is a 1/4 inch NPT female thread attached to an adapter that fits snugly onto the top of an OS .50 helicopter engine carburetor. My objective is to utilize this component to deliver precisely adjustable oil injection for my CNC machine's cutter. Nonetheless, someone else may find it useful, so here it is. Print Settings Printer: Flashforge Rafts: No Supports: No Resolution: .1mm Infill: 50 Notes: Printed with no supports in PLA. The threads demand a relatively fine resolution to be usable. How I Designed This Designed using an original Grabcad file of a valve featuring a 1/4 inch NPT female (https://grabcad.com/library/needle-valve-1-4npt-m-f-hot-max-1) sliced off, and merged with my adapter created in AutoCAD in Meshmixer.
