Hi, thank you for the files.

I'm trying myself to export and fix the 92912 ( 94.3 x 38 R tire) but with no success (I'm not good with meshmixer)
Do you have any hints that my help me?

Thank you in advance

Hello, apologies for the late response and inconvenience, and thank you so very much for your feedback and compliments.

Shapeways has a useful and well organised post on using Netfabb, as well as Meshlab-(another excellent 3D mesh repair tool) for repairing 3D models.

Below are a couple of links to these Netfabb resources, the first link listed below is the post which includes using Meshlab and Netfabb for repairing 3D models, and the second link is a 5 tip tutorial on using netfabb to improve 3D model printability.

Additionally, here's a Pinshape tutorial on Meshmixer: https://pinshape.com/blog/how-to-repair-your-stl-files/

I hope you and others find the links presented above helpful.

Also, a while ago I repaired one of the Lego Technic Parts Collection 2.0 files "model t94" for a thingiverse user via Netfabb.

In Netfabb's repair window, I applied a triangle stitch tolerance of 0.0500 followed by an automatic repair, to the 't94 model' then I exported the model and applied an additional repair upon export by accepting Netfabb's pre-export automatic repair-a window which reads: "Some file formats do not include enough information. This may result in errors."

Also, when I import models I exported from LeoCad into Netfabb, I resize the models by 10.00 using Netfabb's scale tool, then I compare the models with a previous model to which I know is the correct or close to correct scale of a Lego piece. I sometimes move the new model towards the previous model, so that way their studs can align and I can try to determine whether the new piece would be compatible with the previous piece.

Apologies again for the late response and inconvenience, and thank you so very much for your feedback and compliments.. Have an awesome week.

Sorry, here's a LeoCad guide for importing new and unofficial parts libraries into LeoCad:

I hope you and others find the link presented above helpful.

Thanks again for everything. Have an awesome week.

Can you make a model for the hero factory sword blade?

Hello, thank you very much for your suggestion. Apologies for the late response and inconvenience. Unfortunately, I don't think the Hero Factory sword blade model is available on my LeoCad's part library install for export. However, I have found a model of the Hero Factory sword listed on Ldraw.com

http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/4657296.dat

It is possible to use Ldraw's part library with LeoCad. https://www.leocad.org/docs/library.html

So, you may be able to export the Ldraw sword model from LeoCad. I export the models as Obj.

Once the model is exported, I usually scale the models to 10x their size in Netfabb, by entering 10 on the scale tool. I usually export the models as STL in Netfabb after the rescaling, and repair if needed.

The link to the website of the program I used to source and export the Lego parts LeoCad is listed first below, and a link to a list of Ldraw file parts is listed secondly:

Apologies again, and thank you again. Have an awesome week and holiday season.

Thanks, im downloading netfabb now, Have an awesome holiday season too

Thank you so very much for your compliments and feedback. I wish you the best of luck.

How long did this take for you to put together? There are so many parts here that I haven't even ever seen before

Hello, thank you very much for your question and feedback. It took some hours, perhaps around 7-10 hours counting all the uploads, updates and modifications, of both versions (http://www.thingiverse.com/thing:2765212 and http://www.thingiverse.com/thing:3128026 ). The parts were originally from LeoCad, and I exported them as obj, then rescaled and repaired them in Netfabb.

The uploads, updates and modifications of the parts were super worth it, as many people like you have enjoyed them.

Thank you very much again for your question and feedback. Have an awesome week and holiday season.

Hi, could you name all of the files of what they are instead of "t92" etc? like what I mean by it is like the name of the piece "lego_axle_7cm" as an example.

Hello, apologies for the late response. And thank you very much for your suggestion.

I've recently uploaded an identical version of Lego Technic Parts Collection 2.0, however in this newer upload most of the file names were changed to correspond with the names and IDs of the Lego parts.

https://www.thingiverse.com/thing:3128026

Thank you again for your suggestion. Have an awesome week.

Also, I acknowledge that in the past, others have suggested that I change the file names, so I apologize to all who have waited.

And I thank everyone for all their suggestions, patience, and support.

Hello t94 is broken too. My son lost this piece for his Mindstorms...
Can anyone tell me how netfabb works (I'm new to 3D printing) ?
Thanks

Hello, apologies for the inconvenience and thank you for your feedback. Netfabb is indeed an excellent for repairing 3D meshes.

OK I'll have a look at this thanks :)
Do you think you can repair the t94 file for the moment ? My son received the printer yesterday for his birthday, we are only starting using it.
Best regards

Hello, in netfabb's repair window, I applied a triangle stitch tolerance of 0.0500 followed by an automatic repair, to the 't94 model' then I exported the model and applied an additional repair upon export by accepting netfabb's pre-export automatic repair-a window which reads: "Some file formats do not include enough information. This may result in errors." .

Then, I uploaded the updated model into Lego Technic Parts Collection 2.0. I removed the previous model t94 from the selection, and replaced it with the new/updated model of the same name 't94". Additionally, I re-uploaded the previous t94 model, the older t94 model is named "t94-old".

The first link below is the link to the new t94 model, and the second link below is the link to the re-uploaded previous t94 model.

Appologies for the duplicated reply, I thought that the first one wasn't posting, so I refreshed and posted it again, however, I then noticed that the first reply was there after posting the second reply. Anyway. Thanks again for your feedback, and I wish the best of luck to you and your son. Have an awesome week. And delightful printing.

file T102 was broken, (rack 8 teeth with pin holes) I repaired it with NETFABB.

Hello, apologies for the inconvenience, and thank you very much for sharing the repaired model, the solution and your feedback.

Have a magnificent week.

Awesome set of models!

Unfortunately t71.stl is also broken. Slic3r and cura shows some volumes as empty, not solid. Could you please fix this as well?

Hello, I applied an axiomatic repair to the 't71 model' in netfabb and uploaded the updated model into Lego Technic Parts Collection 2.0, the updated t71 model is named 't71 (repaired)'.

Thank you again for your feedback. I wish you the best of luck. Have an awesome week.

Hello, apologies for the inconvenience, and thank you for your feedback. I would try to resolve the issue soon, and I would notify you once the updated file is uploaded. Thank you have an awesome week.

Thank you very much for fixing the part.

Can't say it is fixed completely, Slic3r is still getting crazy when trying to split this part (this is my favorite printing technique to avoid supports - cut the part, print top and bottom, and then glue together), but I was able to cheat it and print the part. So it is ok for now. Thank you.

You're very welcome. Sorry about the inconvenience. Also, excellent work around to getting the part printed, thank you very much for sharing.

I wish you an awesome week.

Hello, apologies for the inconvenience and late response.

The objects may be able to be fixed in netfabb, I suggest stitching a section of selected triangles on the mesh with a tolerance of 0.0500, for the models would be better equipped for the automatic repair tool(s) in netfabb.

Thank you have wonderful week.

You should name parts by look for faster orientation :)

This is a great suggestion, if the image names corresponded to the file name that would save so much time........BTW thanks for much for this amazing upload, I will be giving this a try this weekend.

You're very welcome Gtank1.

Also, I agree that having the flie names correspond with the look of the parts, and or the official name for the parts, is a great suggestion, thank you for the superb suggestion Gophy.

I wish you all a wonderful week and the best of luck.

Super suggestion, Thank you. Have an awesome week.

i have been trying to print the 20 Tooth Bevel Gear but for some reason whenever i try to lay it flat a random layer appears in the middle of the gear ruining the print... it shows up on Cura (latest Version) that is does this... any fix suggestions. i have had issues with other models as well :/

i have managed to print 12T and the 32T seems to not have the issue... if you can help thanks :).

Hello, apologies for the inconvenience and late reply,

I have repaired some of the errors in two of the 20 toothed beveled gear models, using Netfabb, the 2 new repaired models are named: ' t113 (repaired)' and t114 (repaired). They can be found in the Lego Technic Parts Collection 2.0

Netfabb is a good model repairing software, you could examine and repair models quite easily, especially with the automatic repair tools, however sometimes the automatic repair would make unwanted changes to the mesh, like filling an intentional opening in the model, however, luckily the tolerance of the repair tools could be adjusted.

Also, at first, the model 't113' was having some difficulties when being repaired, especially with the automatic repair tool(s) (default repair/simple repair, and the fix holes tool. However, I found that stitching a section of selected triangles on the mesh with a tolerance of 0.0500, section by section, enabled it to be better equipped for the automatic repair, I also used some other repair tools such as fix flip triangles and remove double triangles along the way, note: I didn't really notice any flipped triangles on the mesh, however I thought that it was still a good idea to try the fix flip triangles tool. So anyway after the smaller repairs, when the automatic repair came about, the t113 model came out virtually error free.

Also, when exporting the repaired t113, it went through another automatic repair, to which it returned error free-er, I think.
Hopefully these models would would be more successful at printing.

Thank's again, I wish you the best of luck on future printings. Have an awesome week.

Oops, Sorry, I forgot to actually upload t113 (repaired)' and 't114 (repaired)' to Lego Technic Parts Collection 2.0, before posting the comment.

Fortunately, t113 (repaired)' and t114 (repaired) have now been uploaded to Lego Technic Parts Collection 2.0. Enjoy.

Ok, thank you very much :)
