This is my first foray into designing stuff for my printer. I was spilling a lot of coffee beans when i was transferring from the cooling tray into my storage jar after I had roasted them. All the funnels seemed to be a bit too small, so i designed this one and it worked a treat. I added a version with a spout but haven't printed that one yet, hope it is useful.
