MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
v2 has smaller inner diameter (48mm), to be used with DYS 2030 props which should be 47mm in diameter.
Your props are exactly 48mm? You should be fine with scaling. 1.02 scaling results in 48.98mm inner diameter.
Gap between props and duct will be small and duct effect will have greater results :)
If you have problems scaling, send me your mail and I will send you scaled files.
And if the prints don’t come out good in will make another version with 49mm inner diameter :)
