A regular top for spinning. You might have to scale it up or down depending on the settings of your software and printer.  Any size you want to print it at works. if you like it please upload a print and comment on anything else you want me to make. I use a Makerbot. My splicing software is Makerbot studios. I print it in pla at 190-210 Celsius. Layer height is .1mm for fine details or .2mm if you need speed. Infill is 20% at lowest. If you have a heated bed you can use it if you want to. It shouldn't make much of a difference with this print.
