Yea, I know there are some 3D printer threads on the site already.
I have owned my 85 Carrera for 30 years. I have cussed at many off the shelf funnels over the years. My business partner has a 3D printer, and I bugged him into designing this funnel.
The red funnel was the prototype. We changed to black to look better. The protype did not have a screw cap on the bottom. The black one is the final design, and the cap screws into the inside of the funnel and looks and works great.
No more oil dribbling out of the funnel, or dirt getting in the funnel once you are done with it. Stuff a paper towel in the top, and you will have a nice clean funnel for next time. The funnel on the bottom, has the cap screwed in place. The top one I removed it to show the threads.
The saddle fits over the stock air intake, and it stays in place, even with a full bottle of oil. The tip of the funnel is about as big as will fit in the oil tank, with the dip stick removed.
I love mine. I have had two people contact me about the one I posted in the What are you doing to your 911 thread. We figured up the cost, and time to print the funnel, an I think $25 is a very reasonable cost.
Plus shipping! I will send them out in a box, via USPS at the cheapest shipping cost I can. I will have to box one up and weigh it and figure out what the post office will charge to post the actual shipping cost.
I am not doing this as a money making endeavor, just supply a tiny market for this.
If you have some other year 911, no it will not fit you car as the air filer is different. This is for a Carrera with the factory air filter housing and with a standard one quart oil bottle.
As it is a 3D printed plastic, I would be leery of using it on a HOT engine. I mostly wanted it for oil changes. Put in a quart, and let go of the bottle, and wait for all the oil to drain out. With the large tip, oil should flow out quickly.
Just PM me if you want one. I suspect the shipping will be a couple of bucks. Just PayPal as a gift, and send me the address to ship it to. I have two to ship out now, so I will know the shipping cost ASAP.
