Added V2 version for stock nozzle compatibility and increased airflow. Included is a PDF of the Kapton tape cutouts. Print out at 1:1 and use as a template to cut the tape.

Replacement fan mount for the Ultimaker 2 for use with Olsson Block. Lowers the bottom of the fan mount while improving air flow. I was getting temp errors before with the Olsson Block cooling too quickly. This along with changing the "Fan full on at height (mm)" to 2.0 helped fix this. I printed the fan mount with ColorFabb XT-CF20 and lined the inside with Kapton tape. I've been printing at 240º without any issues so far.

Can you add the step file for the V2?

So V1 is for nozzle with the olsson block and V2 for the stock nozzle, am I right? Or is the V2 an improvement of V1?

Great design btw!

I having some issues with «Heater Error» after using this fan mount. But reducing the fan speed to 50% fixed the problem. Reading forums with similar problems it seems to be the airflow that is to efficient and cool down the nozzle to much, and the heater can’t keep up, and hold a steady temperature when the fans is at 100 %.
