Funnel curved (no support)

thingiverse

To ensure a smooth motorcycle engine oil fill, I created a custom funnel with a curved design to accommodate my air-cooled V Twin. This is my third 3D creation and the funnel can be printed without any support material if oriented upside down. However, be cautious as ABS plastics may dissolve when in contact with engine oil; therefore, print it using Stratasys Ultem plastic to avoid contamination. For reference, check thing:282230 where an ABS-printed item was left in gasoline overnight. Alternatively, coat the plastic parts with a substance that can withstand engine oil for added protection. Share your experiences to help others replicate this useful tool, and it could also be handy for filling coffee machines with water. Special thanks to www.protech.se for making this project possible!
