Finally extracted the gear from stl. &nbsp;Design is here :&nbsp;<u>https://www.youmagine.com/designs/ultimaker-original-extruder-gear</u>

HI, I just need to print the small gear. Can someone advise my on how to cut that piece out of the complete set ? Stl Importer extension of sketch up takes ages in "repairing geometry". I guess I will have to shut it down

Hi, I tried to print the Part on my Ultimaker but it some how did not work. I added support structure. Nevertheless it started printing and it was very messy. Can someone post the setting which should be used for cura?

@ji11, I'm pleased you were able to cut model. Despite the challenges, I'm sure you learned something from the task. I have no idea what upload options are available but it seems like you should be at least able to upload the multiple files as a new design and then link it here as a re-spin. But honestly, this site kinda sucks and it has a long way to go before it'll be efficient and user-friendly! It seems to me that YouMagine was prematurely rushed into release.

Hi Guys, i have been able to take the thing apart finally and would really like to share the files! Do I have to upload a new part or could i add it to those already existing?

could someone do the cuttin for me an reupload the parts here? For some reason i am unable to do this myself... Would be nice for everyone who wants to print on of the parts!

Oh, Ok, but I still can't use the virtual switch to slice the object. I've to dig into it. I have the free studio version. Good to know it is possible, so I've to figure out how only. Maybe there will be some time on saturday while on the Modelbuildersevent...

You don't need support, if you cut out only the part you need using netfabb Studio. The free version (not Pro or the new "Private" versions) only permits planar cuts, so you will need to make multiple cuts and perhaps even rotate the model in some cases before the cut. I'm pretty sure you can make any of these parts lie perfectly flat on the bed.

I understand what you mean, we make use of several mould injection machines and also a Dimension for several years for the rapid prototyping. Because of the injection point in a mould, it is possible not to touch the buildingplatform when put down to lay flat. It seemed to be nescesary to use support. The problem however was the fact it wasn't horizontal, a problem I described earlier at the UM forum. However, I could not make use of the possibility to slice (cut) the part up. Don't know why yet....

To avoid any misinterpretation, I should have said "cut the part up" instead of "slice the part up."

Yes--use netfab to slice the part up to get what you need. You should rotate the result(s) to orientation(s) optimized for 3D printing too. I did not print the parts, but I know they will print. Nylon would be a good alternative to Delrin for some of the parts but the challenges of printing nylon are another subject. I don't remember seeing much need for support to print these parts. I design parts for injection molding too. It's not so much that it's a converted iges file (or other solid model format) as the part just hasn't been oriented for printing. Believe me, injection molding has plenty of limitations too--they are just different from 3D printing limitations!

@Calinb Tnxx. I'll try that in a few moments, good suggestion. It seems to be possible in Netfabb to divide a stl file also, but I didn't discover that possibility yet. One can print the one part that is needed only. I tried older versions of Cura and V13.4 worked out fine with error messages about mesh faults etc. though. I started the print 40 minutes ago to see if it works out. I guess because of the fact the STL design is originally converted from a IGES file and meant to be plastic molded in stead of 3D printing, support all over the subject is needed. If it doesnt work out, it is still a nice showmodel for me demonstrating the Ulti on the Modelbrouwersdag (little confusing to translate that word in English:-) It fits in the world of model building and shows nicely the do's and don'ts. For the delrin part for instance that is needed to hold the spring, you should print it in another direction than it it will be printed in the most logical flat position. Did you print the parts actually? To be continued.

netfabb studio says it has some problems (trivial holes, non-manifold edges, degenerate faces, but it processed fine in Cura for me, after using netfabb to repair the mesh. You could download the free (as in beer) version of netfabb studio or try uploading it to the free netfabb cloud repair service. Mesh lab is another (more difficult to use) option.

Update: Unfortunately it won't be converted by Cura13.06.04. Any suggestions? (downoaded it 3ce)

Nice, Thanks.Just broke the springholder because the delrin wheel on the end was damaged and didn't turn around anymore once the filament was catched by the damaged side.. Could be advisable to make the wheel width the same as the bearing. No problem to draw and print it apart from set, but never the less...

Just started looking for this as the thin wood piece just broke on my upgrade. Thanks!
