SL1 hose adapter

This is a hose adapter for Prusa SL1, for use with flexible plumbing hose with 40mm diameter.
Remove the current backplate, remove the filter, push the new printed backplate, screw it down, filter is no longer needed as the old backcover.
I tried to use old backcover and it's own blower fan but it was not powerfull enough.
I bough a 40mm fan, designed cover with power supply jack and a switch, so you can have the fan running even if the SL1 is off but you have resin inside the VAT.
Old fan is then put using four thick double sided tape a little bit higher, I did not want to remove it as I don't know if there is some kind of sensor that checks if there is a back blower fan.
Cut the pipe about 20cm from the end and mount the fan assembly there.
Optional you can buy two vacuum holders and mount them on the holder part which can be screwed on the white holder that came with the hose so you can stick the hose to the window.
Use the two sided tape to mount the funnel on to the hose, s
