I have started designing an #XCarriage for #Bowden setups and Horizontal Rods that overcomes most of the static and dynamic errors that affect printing during the accelerations/jerks/etc of a 3D printer (discussion here: Started designing an efficient Horizontal XCarriage. Looking for your experience and input).
I hope to improve it and want to get some input from the community.
I have added explanations to each photo so they should be pretty explanatory. If you click each photo you will be able to see the explanations.

Are the coldend-fans blowing against each other? While I like your idea behind the concept, it looks like your design is “overengineered”. Simpler would be better and this doesn’t look simple.
Despite the looks, this is a very compact design that packs in a small footprint quite a lot of features. I wouldn’t design it if I would have found a similar concept that offered these features. Please point me to one if you know, I’d be very interested to compare it.
I have not decided anything yet on the blowers because I don’t really like the bulkiness but the first idea was to have the coldend fand blow against each other and the squirrelcage blowers extract that air and blow it over the printing part… dunno how smart this is though…
I think it’s quite elegant. The opposed blower fans are proven to work (ultimaker). And from experience, one cooling fan is always challenged to meet the needs of the far side of the print (from the fan).
I might replace the blower fans with axial fans for a more compact design … 4 30mm axial fans, 2 cooling the hotend and the other two cooling the part…
Here is one version I am happy with:
