Large Funnel for 100mm sewer pipe root control ROOTX ROOTOX

I made this funnel so I can easily flush my root control pills down the sewer pipe.
Drop the pills into the funnel, pour a bucket of warm water down the funnel.
Dropping the pills into the toilet doesn't work so well as the pills often don't flush... and if you need to flush several times, there is too much water for effective use of the pills.

Depending on how good your printer is, you may not need to print this with supports.
