I first tried to print this at 100% but some of the parts would not print (see the third photo). I ended up printing it at 200% which seems to be the size of the original files included in the .rar archive. To get the outer base to slice correctly in CURA 2 I had to turn off all Mesh Fixes, otherwise CURA wanted to close the center.
I have been unable to motorize this at this time. The link to the motor in JML3134's description is broken and no detailed specification is provided. It has been an interesting learning experience.
