Could not find something like this so i gave it a try. I want to use a IKEA Lack shelf as a monitor and speaker stand on my desktop..
It's a bit too big for my CR-6 SE to print, so gonna make a split version also.

Infil i will go for: 20-30%
No support needed, just rotate the flat side against the build plate.
Each part would take around 12 hours to print on my CR-6, if the plate was bigger ;)

UPDATED: splitted parts uploaded. Print 2 of each parts. My CR-6 SE did two parts in 12 hours, with my slow printspeed.
