No nonsense part cooler for FT5 Titan Volcano BLTouch combination by WalterSKW

NEW Version with shorter nozzles download the V7
With the close BLTouch mount, I needed a new compact partcooler for my volcano.
I want to use large nozzles and change nozzles quite often. The heater block should be accessible for a good grip. Cooler has to fit between BLTouch and Volcano.
This is the result. Design may still change a bit. I did already some tests with good results.
This is the latest version with some improvements : inclination of the outlets, fixation block more robust.
I used a special part to fix the cooler from this design
Added a 6th iteration :
Moved the fan inline with the nozzles to get a more equal airflow through both nozzles. cleaned up/streamlined the initial model a bit, changed the support to give more freedom for adjustment in Y-direction.
Made it a bit longer to the back. Space enough in the FT5.
Picture is still from a beta version
Normally I can keep the bed temperature at 75°C, with the first tests of this cooler I got a thermal runaway from the bed after switching to 100% from layer 20 on (6mm). Same fan.
Trick :
put a layer of adhesive aluminium tape on the side of the outlets facing the hot end. The PLA-testversion didn't even move/flex after printing 3 hours@240°C.
Tape used for insulation purposes works great!
