Adapter quạt thông gió cho Glasbaustein Lüftungsflügel

Why?

This is an adapter for fitting one 100mm wall hole fan to a Glass brick ventilation wing. The wing can then stay open and the fan can ventilate outwards. 

The Glass brick ventilation wing shown in the pictures is probably quite old, I assume, the link provided is similar, but I have not checked: Fuchs Design Glasbaustein-Lüftungsflügel

This is the fan: Air-Circle Wandventilator Top Air

Printing:

print the test part first!

Print it on the ventilator flange: 

you can deacitvate Supports, V1+ has some inbuild supports. I Printed V1 with 0.2mm Layerheight in Petg. The inclination is around 26 degree. 

• There are some round cavities for 10x2mm magnets which i did not need to use. 

• There are some holes for M4 Screws

"Check-Valve" Flaps against drafts 

If you print the flaps (those block inward drafts), you need to put them flat on the buildplate. You will also need axles/shafts, I used four Nails 2x30mm. If the holes on the angled part collapsed, you can ream them with a 2.5mm drillbit.  The STL File contains those  flaps. If you "split to objects" you will also end up with three more objects which are internal voids. you can delete these, the slicer will fill this "space" with infill. The 3MF File has all the parts oriented for printing.
