Well, after 98 hours, 26 minutes and 1 second, the first half of my moms new flower box has finished printing. It took about 2.8 Kg/6.18 Lb And I'm making two of them. It's just a tiny bit under 18 inches high.

Thoughts?
I'm thinking of making a slight modification to it so the bottom is actually a separate piece that just drops in. That way most of the bits that have not straight lines don't have to be printed on my z18 with (compared to modern printers) abysmal acceleration that cant be changed in the default slicer. Instead I can print 4 9 inch tall sections of the drain holes and reservoir on my dad's K1 SE and the z18 can do the tall 18 inch sections which are mostly straight lines and it will be able to accelerate up to whatever speed I want it set to basically. Overall it should print faster and better utilize the strengths of each printer.
