Only problem i see though is, there is the same problem as with the first design of the feeder. What would happen if the PLA got a bit thicker lets say a bit over 3mm like 3.05mm after some months of storing it at home? Or even just 2.95mm? That would definitely lead to problems as there is no space for the material ,of where the thread has cut in, can go.... Another Problem as far as i can see in your last picture is you will need to use a gear onto it and there will arise quite some design problems on how to get the threaded part to stay in place and in touch with the driving gear. With the Thread itself i personally would go for a special one ..... otherwise this idea would theoretically bring many problems in everyday use. I personally would go for a M3.3 or 3.4 with p=0.7.

Update for my Spool holder design I just added Spool Covers so the filament cannot unspool far and hop off the Spool. Here are some pics Sadly that Spool Cover Snapped but it represent pretty well what i intented though.... since then i made a special version to prevent the snapping for ABS

Strings: Lack off Cooling/ you need a bigger retraction/ dirty nozzle "Bubbling": Bad bed leveling/ uneven bedplate.... the big "bubbles" on the right are from sudden pressure release from the nozzle which has built up because it could not place it before...

Just asking but has anyone ever had problems with self unspooling filament that entangled itself?

When i do a high quality Print these are my settings: Bed temp: 45°C Nozzle temp: 220°C at 1st layer after that 200°C 30mm outside layer 40mm inside layer 50mm infill speed 1.2mm Shell and 1mm top bottom thickness atleast 0.06 Layer height

My grand design of the Spool and Feederholder is now finished and ready for printing One Can find it here: https://www.youmagine.com/designs/spool-and-feederholder

Damn the last days were exhausting..... sorry that i have not uploaded the final stuff for the spool/feederholder yet.... i just made the changes and now only have to reprint one part to make sure the issue is really resolved.... even if it was just a minor one.... but damn is it hot today where i am 26 degrees..... could it not be 20 degrees less?

I had them assembled for something else before.... they are powered by an old handy charger i missuse ;D i was just to lazy to disassemble them

Here you go needed to black out some stuff though.

Okay folks. Update time: Ok just as a foreword, the parts are usable but still need some finetuning. That will be done easily though. I just hope nobody started printing this And now Photo time Isn't she a beaty with the feederholder? The fanholder still needs to be done, but for now i can use the rest of the brim to hold the fan And here a first test with the new spoolholder with 140% speed. I think i will never go faster because 140mm seem to be the point where adhesion problems begin. That i will leave to someone else to fiddle around with. The final files will be uploaded to youimagine in the next day(s) so stay tuned

You described it well enough so i know exactly what you want..... only problem though..... time..... and a damn long project list..... and this would not get an important flag..... btw i thought also about the temp problem..... thats also why i would use a small wall. and a 60mm fan atleast yes but now please in printable without support you could always contact me over skype if you want. contact details are in my profile

Specs and models: http://umforum.ultimaker.com/index.php?/topic/4393-ultimaker2-feeder-system-improvements-and-ideas/page-15&do=findComment&comment=42956 the ballbearings are attached via spacers. The feederholder is currently missing. It should be finished in about 10-12h. The all i have to do is printing the 80mm fanholder and it is finished.

Ok first parts of the Spoolholder are fninished and work as intended. Just a little more time and the test is done.... maybe 1 to 2 days. Here is a pic of the stuff that is printed so far and assembled:

Just some comments. You have to print the Covers in 2 Parts and screw them together since the total length is 23.5cm. The fan inlet would not need to be modified. just mirror the part in Cura. the hard part will be nut used on the side to screw the cover against the sidewall of the ultimaker. What nut do you want to use? Why 3mm? there is no physical stress on that stuff. 1.2mm should be plenty.

try to download again recoded it in deflate instead of bzip2

Due to lucky circumstances i had unexpectedly some time on my hands and got to redesign my spoolholder. I packed all the extras in it mentioned in my previous post. Although the feeder holder did not make it to the middle and was just tilted by 45°. The ballbearings to be used are 6808 61808 40x52x7 mm ones. So i would like you guys to have a look at it and say what you think about it. Download of the whole thing: https://dl.dropboxusercontent.com/u/90634021/Spoolholder.zip And fo the ones that don't want to download it a nice litte pic.

Me neither..... for one reason....when you would print in the backside of the printplatform you still would have a very hign angle of 70-80° which makes no big difference to the actual design.. only that you changed left and right with back and front. And yes i know my spoolholder design leaves wished open. On my current list of things to do on it are: -Add ballbearings for the spools (less friction) -move feederholder to the middle of the spoolholder and tilt the feeder by 60 degrees (allows for a more compact and less material intensive design, also less stress on the bowden tube) -merge it with the adapter ( more sturdy design) -fanholder Sadly i dont have that much time on my hand currently which makes progression rates on my projects a little bit slow. So if you want to take it on i and probably everyone would be very much oblidged

Ok i have to admit i feel lucky to have a 3930k in my pc otherwise the converting of the step files would have taken forever. And i have to say..... i am fine with the general design but some details are a little bit off as far as i can see.

May i take a guess why it did not work? I would say you guys had real problems aligning the head on the same height. Simply somebody seems to have forgotten the thread above the nozzle would not always start at the same position. Which is a problem since the case for the heater, the temp sensor and the nozzle are one piece. There are 2 ways i can think of right now to solve this problem. Both do not require the thread since the full package will be attached in a "neutral" way.

Could you atleast change the Ready for a Paid in the Orders? The Ready can be really confusing when you don't know what it means in your shop. Never seen it in any other shop.

Cubify?

i would like to take a look at it. You could send me the files? I mean the Solidworks ones

First design of the radial fan i will use together with this motor: http://www.conrad.de/ce/de/product/229022/Motraxx-Elektromotor-X-Train-124-L-N-12-V-Leerlaufdrehzahl-229022?ref=list#download-dokumente Design can be downloaded to look at here: https://dl.dropboxusercontent.com/u/90634021/35mm%20Radial%20Fan.STL This design will be optimized for the UM2 since there are some space Problems with the sidepanels and the X/Y Stepper Motors as well as the Bed Plate with the Ultimaker² line on it. I will recommend probably to take off the X/Y Motors though. Anyone up to supply me with a nozzleshield as it is specified in my previous post? Sadly i lack the material and especially the tools to do that thing.
