[What is the best printable fan duct for the Ultimaker 2 (+)]

Hello all...

Im having a hell of a time getting overhangs to print well...
The main problem is most probably the cooling with the original fan ducts on my UM2+

I have been looking around several 3d resource websites to find a good printable fan duct...

Any advice and expierenc is welcome !!!

Added a temp tower as it prints now for insights...

[Picture / decoration wall hanging rail system.]

Hello all, my FIPO here

I wanted some sort of rail to hang pictures and other decorations on my wall without making holes in the wall every time... (except those for this system).
Wall hanging rail systems exist, I know, but they are expensive and most look frikkin ugly
 

So I had an idea with a plank and some supports and hooks, looked around on thingiverse and saw a design that sort of matched my idea but I was not satisfied with the mounting method and the hooks needed a redesign to fit my esthetics too
 

Here's the resulting easy wall hanging system design on Thingiverse with descriptions etc:

I printed with 0.6mm Nozzle because it gets sanded any way in my case

Enjoy & Happy 3D Printing,
Peter Lunk.
