At the same power level, the centrifugal fans give more air flow, have no vibrations and are a lot quieter vs axial fans. Warning : Fan duct Olsson block adapt only ! for the old stock UM heat block that may be needed to modify the hight under the heat block, use step files eventually to any modification.

Not sure if this actually help cooling... There is only 1.66CFM output each on these 35mm fan where the stock fan on UM2+ is 2.2CFM each.
You can get quality 30mm axis fan with low noise at 2.8CFM fair cheaply, where the best reasonable priced 35mm Centrifugal outputs 2.2CFM.
Centrifugal fan does have higher pressure, so I guess they are eventually comparable.
Is there any thread on a forum or any notes somewhere about the developement of this ? Or a comparison, even anedoctal, with the new stock 2+ fan shroud?
Your design looks awesome!
I have 40x40x10mm 12V fan, could you easily change your part so it could be compatible with those?
- Printed on:
- Ultimaker - The Ultimaker 2
- this upgrade is really good
- had some problems with the clearance first, but then printed a modified printhead bottom part and everything works
I had not experienced this problem
would you please to precise more the X-stop issue,
if it's possible, a picture will help me
I printed the fan shroud and it looks really great. Unfortunately the shroud interferes with the x-stop on both sides. How did you solve this problem?
