Design Challenge! UM3 Spool Holder Extension (Adapter)


Recommended Posts

Posted (edited) · Design Challenge! UM3 Spool Holder Extension (Adapter)

Got my UM3E -- discovered that a good amount of my filament spools will not fit when making use of dual extrusion.

Looking for some motivated designers to create an adapter between the filament guide and the reel holder to lengthen said item.

Looking for Ultimaker to share their ideas here and maybe some files/design specs to speed up the design process~

I'm not fast at all when designing (I take the methodical, incremental approach) so hoping for assistance here if no one else steps up~


While a longer reel holder could be another option, I'm looking for a cleaner option; like an adapter.

Reason for this is that this adapter can be further iterated upon to accommodate smaller spools like taulman nylon.




Who do I need to talk to in order to get access to the design files of the revised reel holder in the UM3?

I'm hoping to put together a sketch of what I'm attempting to accomplish here within a week or so (as life permits).

All the design files of the UM3 will be released in a few months. I don't think they'll give the files out earlier than that.

I've been wanting to re-design the spool holder since the first time I saw it. I have a few ideas. Question is if I'll be motivated enough to finally sit down and make something. Motivation for stuff like that has been lacking for me lately which sucks :( This post did spark a couple of ideas though...

I think when redesigning it there are 2 things to do;

1) have an adapter to raise the spool about 5 cm. the standard um3 has dropped the spool holder by about 5 cm which is enough to prevent the large spools to fit.. so that is no 1.

2)have an extension to have both the large spools as well as the small spools.

that being said;

i found this a real issue.. but now after a couple of months i don't see this as an issue anymore..

i just use the extended um3 that has the spool holder high enough for the larger spools i use. i have no interest to use a large spool together with a smaller spool... this would either mean a super hugo dual color print, as in 20+ days.. or it would be with PVA and the only real PLA i've found to be working perfectly with the PLA is ultimaker PLA which does not come in high spools..

so I don't think I'll actually be using the larger spool holder...

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
