A8 plus PSU cooler guide

The fan of the PSU was blowing on the objects on the bed. Especially with higher objects not good and leads to disforming of ojbjects.
So I made this guide to make the flow out of the bed, up and or back.
By setting the nobs on the guide into the openings on the PSU-block you can set it to more-open (large structures could bang into it) or a bit smaller opening (keeps the whole bed free).

The STL comes with supports, cut those off before using. Printing can be done without additional supports.
