From video description:
It is about time to provide proof of Wally printing a large object. If you look closely you can see the bed going up and down to adjust for the bed level. It took about 7 hours to print the vase. It is 100mm x 100mm x 145mm. I used a .4mm nozzle and did .2mm tall layers. I used default slic3r speeds. I have gone as much as 4 time faster while I was watching but for an unattended print like this I wasn't as adventurous. I suspect that I can go about 2 times as fast before surface quality suffers.
