Funnel for joylent / powder

Makes it easier to pour any powder into a shaker
The lower opening is 78mm in diameter

I made it to use at work, where I have containers with a ready portion, and this makes preparing it more or less spill-proof :)

I used a fine sandpaper on the inside to smooth it out a bit

Update: Added a file with 0.8mm shell
I have not printed this yet, so please leave a comment if you try and tell me how it went :)
