Bladeless Desk Fan Base for 12 cm fan

I designed 12 cm fan base for the original scale of Dylman3000's Bladeless Desk Fan since I have already printed it.

I strongly suggest using qboney's 12 cm Laminar Flow Fan plate as it helps a lot.

Prints without supports.

UPDATE: Added a lip modul under the fan so it is even more of a beast now.

Included the blender file. I used mostly boolean modeling and some light mesh edit. Feel free to improve anything.
