Oil drain pan breather- screw on

I hated the push on breather that my drain pan container comes with from the factory since it never pushed on and always leaked no matter what. I designed this to screw in and mostly stay in place, allowing you to screw off the drain and screw it back on when done. In future versions, I will upload a holder for the cap to prevent it from getting lost.

Please note: you push this design into the hole that remains after you remove the push in breather. This design is tapered so that it will sit fairly snug, HOWEVER, it is being held in by friction and will spin if excessively tightened. It will still loosen but there is no need to go crazy tightening it down since the tolerances are super tight and it will not leak past the cap- even if a bit loose. You can always glue it in if you feel like it.

I have used PLA for this for two years and it has held up just fine since it doesn't actually come into contact with oil, just oil vapors. I would recommend printing in PETG or ABS / ASA if you like to change your oil immediately after driving though for better long term reliability.
