Help with a design?

by RVJimD

Found this group and it seems like a great idea.

I have used Tinkercad just a bit and then started using Fusion 360. I knew I wanted to learn enough about whichever program(s) I adopted and I felt that Tinkercad had too many limitations.

I made a video the other day regarding a hobby projects I am trying to design. My hope was the video (pictures) would describe the goal better than I could do with text alone. Here is the video link, I would love some pointers if anyone has thoughts on the topic after watching the video.

Thanks

Centering pieces on other pieces

by GhostMouse

Hi everyone! Playing around with a design and getting a bit frustrated. I want to center one of the objects on top of another but I cannot figure out how. Using TinkerCAD. It's difficult to move things along a certain plane, I cannot seem to click an arrow and shove a thing a tiny bit that way or anything. Does anyone know how I can move something in relation to something else rather than in relation to the grid?

Wood Filament Nozzle

by Soundwave12345

I got some wood filament for Christmas, but am unsure which nozzle type to purchase.
Ruby is too expensive ($90)
stainless steel is cheaper, but will wallow out faster than higher grades.
I know I can't use a brass for it.

Super n00b question for n00bz

by GhostMouse

So... how do I make sure my design is the right size? There are rulers and stuff in TinkerCAD (all the free software I've amassed and I still play with that the most, oops) but they don't have a unit, just numbers. Is it mm? in? cm? kilometers? Or is that something that gets sorted in the slicer program? I don't have my printer yet but when I get it, it's got a pretty specific set of dimensions it can do so I'm trying to make sure stuff I design fits into it.

I came from freecad, scetchup, now I use Design Spark Mechanical

by Copyright

They reason why was:
I had no skills in CAD/CAM and don't wanted to learn it "the hard way" by expensive tools and training.
DSM is free to use and very easy to learn.
You will improove your skills with every design you do.

I learned to love the layers, objects can be combined or seperated with many supporting functions.
Also "problematic" things like a text (any windows font) on a surface is no problem with DSM.
One of the best features of the program are the multiple import formats supported.

You can open:
DS Mechanical-Data (.rsdoc)
ECAD-Data (
.idf; .idb; .emn)
Object-Data (.obj)
Scetchup-Data (
.skp)
STEP-Data (.stp; .step)
3D-Print-Data (*.stl)

Just have a look on my designs here in Thingiverse

Kind regards to you all,

Over hangs

by Soundwave12345

I would like to know about the average amount of overhang that can be allowed with a required support structure of some kind. I'm trying to design some new types of things, but this would really help

Repairing STL Files

by DarthCoffeeBean

Firstly thanks to all that suggested DesignSpark Mechanical. I've largely moved to it from sketchup and find many things so much easier now.

Also wanted to share a tool I found for repairing STL files. There's a file I downloaded from thingiverse that I just couldn't get to print and couldn't figure out why. As it was just one part in a 30+ part model and I'd already spent a week printing bits, I couldn't just give in. I found MeshFix (https://sourceforge.net/projects/meshfix/files/). It's a windows only command line tool. Just run "meshfix.exe -j brokenfile.stl" and it will attempt to repair your model.

Also found some online repair tools, but the only one that could fix the part was meshfix. Hopefully helps someone else out at some point.

Where I've had an issue recently though has been with STL files I've gotten from others that have errors and cause problems printing due to surface holes, internal faces, etc, etc. Opening up someone elses design and finding and fixing the issues can be painful

A few of us built 3D Orchard. The platform has free built-in CAD

by Orchard

Hey guys, we'd love your feedback on 3D Orchard ( https://3DOrchard.com ). It's kind of like Thingiverse with CAD built in. It's still in Beta, but three of us have spent the last few years (and our own $) building the platform to encourage the world to come together and design in the open. We're makers with engineering backgrounds who understand how empowering it is to have FREE access to these kinds of tools.

The built-in CAD tools are free for both public and private use; and not just free in terms of cost, but also in terms of model access. Anyone can download the models in our own internal format (.BREP, which is the same, I believe, as other programs like FreeCAD, openSCAD, etc). So your models can't be held hostage. The actual CAD tools are browser-based so they are readily available with the models (and on any device). Not to mention, there are no updates, downloads, installs, or licensing headaches. Once the model is loaded into the CAD interface, you can continue modeling, even if you lose a wifi connection. But you will need a connection to be able to save it back to the server.

You can chat directly with us with the green button in the bottom right. Or access the CAD for free (and without signing up) at: https://3DOrchard.com/app/CAD

There are built-in youtube videos in the help (?) button on the site, and written tutorials at: http://learn.3dorchard.com/tutorials

Here's the platform, 3D Orchard: https://3DOrchard.com

Design Creation Question(s)

by nmsr1196

How would I create a design for the part in the picture? Meaning the curves. How to create then. How would I get the right angles and such?
