Mower Oil Filter Funnel

I made this oil filter change funnel for my riding lawn mower to prevent making a mess when removing the oil filter. The location and orientation of the oil filter make it difficult to change without oil dripping everywhere. My riding mower is a Husqvarna YT22V46 with a Briggs & Stratton INTEK 22 h.p. engine. This funnel should work on other mowers as well with the same or similar engine and oil filter location/orientation. 

The funnel has threads for a 12 oz. Gatorade bottle to use as a catch can for the oil that spills out when you remove the filter. This also makes proper disposal of the oil much easier. I recommend draining the engine crankcase first just to limit the amount of oil that spills out of the filter.

I have included pockets for qty=4 6mm X 3mm magnets (optional) to help hold the funnel in place. They are a press-fit due to the orientation of the pockets when the part is printed. A small drop of glue/epoxy is still recommended to keep them secure.

[UPDATE 3/25/2025] - I have updated the print profile to include an optional catch can (plate #2) that can be printed if you do not have an empty 12 oz. Gatorade bottle to use. I also made some small changes to the funnel portion to reduce the possibility of leakage on the outside of the threads. If you have already printed the funnel part, it will still work with either catch can but may have small leaks on the outside of the threads. The funnel part still accepts the empty 12 oz. Gatorade bottles as before as well as the included printable catch can. I would not recommend using the printed catch can for long term storage of liquids due to the likelihood of seepage between the layer lines which is typical of FDM printing. 

Also, I recommend using PETG due to the better chemical resistance and layer adhesion verses PLA. PLA will work but may not be compatible with any cleaning solvents that may be used.

After printing, remove the supports from the funnel part making sure to remove any support material in the threaded portion with a small pick or screwdriver as shown in the picture below.

Printing tips:

·         0.20 mm layer height - variable height is used to improve quality of the threads

·         15% infill

·         Support required (on build plate only)

·         Brim required
