I designed this to be printed on a Creality CR-10 (300 x 300 x 400) in vase mode. If you would like to scale it up you will be fine with vase mode. However...
WARNING
If you have a smaller format printer and need to scale it below 75% I do NOT recommend vase mode as intersecting geometry will cause the slice to fail.
It will slice/print just fine at any scale set for 0% infill and as many perimeters as you have time for. All angles are 45 degrees or greater so infill and support are not needed.

Enjoy!
