Hello and yes :-) It is of course possible to make adjustments for 40mm fans. But with identical positioning of the fans, the entire print head will need much more space. This will mainly cause problems when several objects are printed simultaneously. The slicing software used must know the new size of the entire print head so that no collisions occur. The building area will lose at least 10 mm to the left and right. The fans of the UM2 are 10 mm high, but there are also higher and lower 30 mm fans. Higher fans have better air flow at identical or lower speed, resulting in a lower running noise overall. Adjustments for higher fans are in my opinion the better choice, since then only some building height at the Z axis is lost. The time required for such an adjustment is significantly lower, but I have no time for this either.

Great Design! Is it possible you make a version for 40mm fans? I use 2 40mm Sunon fans, which are very silent.

Hi Gothampixel presented on Thingiverse a make of CPv9. For me it looks as if he uses the Olssen heater block and his commentary is as follows: "Brilliant design! But you have to be careful of the fan coming on too high When the build plate is close or the temp will drop Quickly and cause a heating error. Printed with mine Colorfabb's XT red " So yes, it works :-)

Does this design fit the Olssen heater block?

• Since today 03.17.2015 revised versions are available. Now there are fan-cages for the original version Ultimaker 2 CPv9(A) and also for the newer version Ultimaker 2 with the ~ 11mm shorter print head (CPv9(B) and CPv9(C)). The downloadable files are marked accordingly. • The original Ultimaker 2 version can be equipped with the variants (A), (B) and (C), but the Ultimaker 2 with the shorter printhead needs the variant (B) or (C). Variant (B) and (C) I have not personally tested.• Variant (C) is closer to the original design (A). The air ducts are again 50/50, for a possibly better object-cooling / print- head cooling. Please test and compare the variants (B) and (C) and give me feedback. I currently have not the time for intensive testing. I use a very long time variant (A) and there is so far no problems to report.• Please give me feedback if something does not fit and do not forget about the most current information in the corresponding forum thread.Markus (mnis)
