I tried printing these and they are coming out small. Do I need to scale them up for the right size?

You can make Gundam bots.
Wow. Go figure.

Hello, I am new to this and had a couple of questions. I am using Cura 15.04.2 with a printrbot play. I printed one of the core bricks and was successful (mostly). 3 of the four longer sides were sharp and printed well but one side was kind of "mushy" looking (I believe this was the side facing the bed). I was looking at the photos above and in the photos there is a support of some sort around the base on the printer bed. I didnt get anything like that on my finished print. Do I have to somehow enable this in the software? Thanks for your help.

Love this idea. I'm having trouble printing the bricks on my mini kossel so I'm reverse engineering some of the parts to make some modifications that i think work well for my printer. Just wanted to ask about some design decisions. 1. Why did you opt to make the dimples hollow? does it provide some ability for the dimple to be compressed allowing a tighter fit? 2. why did you opt to make the parts hollow instead of just letting them infill with whatever pattern the user chose? 3. I'm getting cleaner prints with my PLA, maybe just my settings, but I have more colors in PLA. do you prefer ABS because its a little softer and molds a little to the LEGO bricks if the print is a little off? Thanks for the design and thanks for taking the time to answer these questions.

Thank you rsee360 for the message :) Have you got the frame printed out in PLA? Look forward to seeing your modified version. Below are my answers to your questions:

  1. Dimples on the studs allow you to attach parts compatible with building toy.
  2. I set the parts printing hollow to save the filament consumption and printing time.
  3. I haven't yet tried them in PLA, but the result of ABS is fine to print LEGO-like bricks.

Hi I'm new to 3-D printing and My school has a printer would I need to change the scale of the models to print to make them compatible with regular Legos or should I just leave them alone.

Hi, the 3D models are the right scale to compatible with Legos. The designs include the supports for 3D printing and can easily be removed after printing. A quick reminder, need to place the 3D models correct position on printing bed like the pictures display shown above.

What percentage infill is generally used? Should I print this with a raft?

The 2x2 ball joint has no support on it as well.

I'm asking this while test printing one out at 20% infill. I'll be sure to tell you how it goes after.

Sep 19, 2015 - Modified Sep 19, 2015

Hi, the models have no infill they are empty in the center. The designs include the support, but a few models in my experience need no support such as the 2x2 ball joint. Hope you have them printed out nicely. Happy printing.

Looking forward to printing this! But I can't find any list of the parts needed to build one of these robots (I have a hard time identifying many of them from the pictures as I'm only just getting back into lego). Thanks!

Hi rockets,

The building instructions for the frame are available to free download at www.herodesignstw.com. You could also email [email protected] to ask for the complete building instruction including list of cover parts 360+ pcs for these robots. Our frame designs could help you build articulated mechs with Lego parts compatible. Happy 3d printing and enjoy building!

The link to the instructions doesn't seem to work. Gives me a 404 error.

Hi mushoo, thanks for your message, the error has been fixed. You will have no problem link to the download page and find instructions of the frame. http://www.herodesignstw.com/#!3d-models-free-download/c20me


I am completely new to 3D printing but I have some knowledge about it. I would like to print this model, however I do not own a printer. My teacher at school owns a maker bot and allows anybody to print anything they wish. I was just wondering if these files are compatible with all printers or just maker bots? And also what specific plastic is recommended for this? I wan't to make sure it the skeleton is strong and durable for building. Is there any external programs needed for the files? thanks.

Hi there,

Our studio's printers are Up plus 2 and XYZPrinting da Vinci, and the material I use is ABS filament. The 3d designs of version 0.9 in stl include print supports and extended bottom. You can easily remove the supports after printing. Whereas the version 1.0-2 I removed the 2mm extended bottom for makerbot user to try. Please be sure the printing orientation of the print supports will stand straight on the print bed. If the printing is successful, you would be able to use the frame to build with Lego bricks.

I apologize if these are dumb questions but I'm a 3D printing newb and the supports for these stl files confuse me. When I load them into Repetier they look like the images I see in the thingiview. I see the thin cylinders running up the sides and protruding a little past one end. It doesn't seem like it would be possible to print this design, as the entire brick would be hovering above the bed on these thin stilts.

Then I look at the printed samples in the gallery (http://thingiverse-production.s3.amazonaws.com/renders/d8/47/08/24/c6/3DP-3_preview_featured.jpg) and it shows a completely different support structure that's not in the STL files.

So, how do I go about actually printing these? What orientation should they come out, and do I need to let slic3r add supports?

Thanks for the great work, btw!

Hi there, thank you for downloading our 3D files and the positive comment! The stl files are the latest version 0.9, in which we made some design adjustment for the print supports. They help the studs of the brick to shape better, and they can be removed easier after printing. Some pictures in the gallery were taken earlier, so I figure why they got you kind of confused. Our 3D designs come with the print supports, so it might be unnecessary to add supports. Different printers the result may vary though. But please be sure to have the print supports stand upright on the print bed for printing, as some bricks will lay on the side and some on the end.

Awesome design, I would love to print these out, not sure if the support is necessary, can you make files available without the support?
Slic3r will add its own if required.

Thanks bobwomble, look forward to your print! The support design should help and provide a better chance to get a good result. So I would suggest that you print with the support. The shape of studs will look better with the support. Without proper support, 1x3x1 and 2x4x2 might easily to fall off during printing.

Hi, It is amazing!. Could you upload the cover parts?, It would be awesome.

Thank you IzaskSystems. Very pleased to know you find MyBuild core bricks system interesting, as it would a cool addition to Lego bricks. We've almost completed the 3D models over 300 pieces for the cover parts. In the meantime, we have the instruction in pdf file including all the Lego parts list on our website, if you would like to cover it with Lego parts. We might upload cover parts stl files later if you're interested, though that's gonna be a long time print.

We also printed the brick with no extended supports, the result is fine. We save some time removing the supports afterwards. Thanks for the suggestion, cap_herf. We will update the files to version 0.9.

Sep 3, 2014 - Modified Sep 4, 2014

This is great, I'm in the process of printing one up. One question, why did you extend the supports you added by 2 mm beyond the natural bottom of the part? I think it would print better if these supports were aligned with the studs. Nice work on this, I'll take a pic when mine's done.

EDIT: I'm guessing you made the supports like that for a non-FDM printer. I'm making an edited set of files with the extra 2 mm removed.

did you have any luck making a set with the extra 2mm removed? i haven't had any luck trying to get these to print with a makerbot replicator 2.

Give me a day or two. I'll be back with the extra 2mm removed and uploaded, and see how that will work for you.

Thank you cap_herf! Glad you like it and love to see your make! We tried the extended supports to see if it's easier to pick the printed brick up from the platform, as well as to remove the supports afterwards. We are also trying different ways to print it better. We are using FDM / ABS material.

Thanks for your positive comment!
