A simple question, what are the exact screw types used to mount the 2 fans to the fan shroud on the UM2 Ext?

I've looked over the bill of materials and I just cant see it. I'm sure the information is staring me in the face :)

I ordered a Olsson Block and some nozzles and want to print off a new fan shroud, but I think the screws in the old one got damaged when i did another mod recently. So I want to replace them.

Thanks

    There have been a couple of different kinds used. Most recently they're using a machine type screw. The easiest would probably be to simply measure what you have, no?

     

    Yes, that would be the sensible thing to do :)

    I was hoping to get ahead of it and order whatever I need before I take it apart. I have time anyway as I only ordered the Olsson Block a day or 2 ago and that will probably take a while to arrive.

    Thanks, do you know the type of screws used. As in 10mm m4, m3 etc etc

     

    Well, it's not a metric thread like all other srcews, its just a chipboard panel (or "SPAX") screw.

    The 2.5x16 defines the outer diameter and the length in mm. You should get it in any hardware store.

    Here is an example with image and a sketch with dimensions.

    Thanks, I reckon if i cant get them with all this info then I should just retire :)

    By the way, good job on that custom firmware. I've been using it for a while now and it's a lot better than the default.

    Print this one, and you won't need any screws to hold the fans in place.

    It's also one of the best fan duct designs. If necessary, print using Kisslicer to adjust using "Inset surface" to get a light press-fit with your fans.

    It's really hard to tell which is the best design for the fan shroud. At the moment I'm using the Venkel shroud on my Ultimaker 2 Ext. It seems pretty good.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
