This is the first thing I created in MeshLab and I am really pleased with the results.
My wife wants a bowl of these different sizes and colors on the table.
The cat also loves playing with it, it has a peculiar roll and sound in a tile floor.
If you start by making a small ball you can put it inside a large ball when printing(make sure it is below the print head height when inserted.
I use Simplify 3d as my slicer. I import it in, scale it to the size I want and rotate it so there is a good footprint on the bed. I have my start height at .2 mm so it just sits flater. See image from slicer if you have a pentagon flat on the table it sticks really well.
I just use Glue stick and 40 degrees C bed temp.
.2 mm layers
2 bottom, top and perimeter layers with 10% rectilinear fill.
No support needed.
I have a big fan blowing over the print area.
Very few fluffy bits to clean up.
