Dospel fan spacer STYL II 150 WCH Bathroom fan wall mount 150mm

I wanted to mount an bathroom moisture sensitive extractor fan to the inside off a wood shed.

This puts the fan on an offset on the wall on the inside. There are 4 support corners with mounting holes for the fan. The 8 mounting tabs are used to screw the spacer to the wall. I intend to use it with a 150mm pipe in between the fan an the outside cover on the exterior of the wall.

The fusion file is included. It is a bit parametric.
