M9 to M5 converter for bowden ptfe pneumatic push-fitting

I ordered a ptfe tube from China and seller shipped it with same M9 connectors on both ends which is not what I wanted because the extruder side on my prusa i3 requires M5. So made this step down adapter for it. This will convert usual M9 OD PTFE connector to M5 aka PC4-M5. The recommended resolution is 0.1 but 0.12 will do just fine.
