Botanical Portal (less friction, easier print)
prusaprinters
I just added some nubs on the inside of the top and bottom to lessen the surface tension. Then I thinned out the center part. I also modified the moving parts, they were a little tall and skinny to print without perfect tuning. So I combined them with their top rings and split them in the middle. You'll have to glue them together, but you would've had to glue the top rings on anyway. I used some super glue and used the “Middle Thingy” to make sure they stayed aligned. So hopefully it's a little more newby friendly.
