Quick and dirty offset funnel I use to fill water jugs with ice from the refrigerator. I printed with a raft. Your choice. As printed it comes out to be around 4 inch by 2 inch. Of course that can be resized to whatever your needs.

If you found this useful, please donate what you think it is worth to my paypal.me/Midvale1955. Help cover the time of design.

Thanks, Enjoy!
