Part dimensions and drawings Hello. I'm just starting to research what I will need to do to make the reprap 1.0. I have access to a full machine shop and I was hoping to machine most of my parts from scrap metal for the Cartesian Bot and the extruder and whatever other mechanical parts there are to save on cost and to make it a little more robust than the plastic. I have found the stl files and downloaded them, but I am unable to get any dimensions from those files. I was wondering if anyone new where to find drawings with dimensions. Solidworks files would be ideal for me, but any drawings that are dimensioned would be greatly appreciated. https://reprap.org/forum/read.php?4,13453,13453#msg-13453 Sun, 07 Jun 2026 12:47:44 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,13453,15956#msg-15956 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,15956#msg-15956

feel free to check over the drawings, some dimensions may be incorrect or there may be other mistakes, so I'll update them as need be. I also modified some of the parts to make the extruder easier to make with a mill and lathe.

Disclaimer: keep in mind that these drawings are really really lazily done. I left off a lot of things that should be there, like datums and geometric tolerances. in fact, I pretty much left everything without tolerances. I assumed this would be fine because the tolerances are rather loose to begin with, and the drawings aren't going to a vendor or anything like that anyway.]]> slade Reprappers Wed, 20 Aug 2008 23:01:53 -0400 https://reprap.org/forum/read.php?4,13453,14944#msg-14944 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,14944#msg-14944 Kyle Corbitt Reprappers Sun, 27 Jul 2008 01:36:36 -0400 https://reprap.org/forum/read.php?4,13453,14903#msg-14903 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,14903#msg-14903 img504.imageshack.us]

Right now I'm having to hotwire the Stanford Linguistics parser to do some things I want in visual studio. The damned thing is 3.4 million lines of Java code, so I'm not real excited about putting a wrapper on it and accessing from Visual Studio that way. I've got a French app that does that except the damned thing is written in Visual C#.

Possibly. OTOH, since this flamelet war started, I've got Tommelise 2.0's USB link between the PC software chain (which includes AoI) and the Pic 18F4550 controller board's EEPROM buffer running slicker than a greased snake. :)-D

Great, I know many of us will appreciate that. If you make models of the extruder pieces in a sane (non-AoI) program, I think that you will have many thankful people. I for one would appreciate a model of the extruder as a STEP file, so I can mill it (assuming I get my mill working, of course!) The other bits are available as an IGES file, but the extruder was created directly in AoI.]]> Kyle Corbitt Reprappers Tue, 08 Jul 2008 22:37:23 -0400 https://reprap.org/forum/read.php?4,13453,14059#msg-14059 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,14059#msg-14059

ronanwarrior - thanks, I'll try that when I get the time. pro/e and myriad seemed to have a problem with files that were polygon maps of surfaces, hopefully sketchup will be better.

I uploaded some screenshots which I took quickly in AoI to estimate the part dimensions. I'll see if I can get something better from sketchup or pro/e, and I'll upload drawings after I have decent models.

Yeah, your messages had a strong flavour of crying for the moon rather than trying to get the job done. Here's a news flash for you. This is an open source research and development project. If you expect that things are going to be as slick and easy as they can when you've invested $30-50K in a commercial 3D printer and $3-5K in top-of-the line commercial 3D modeling software you're not going to be happy working on Reprap.]]> Forrest Higgs Reprappers Sun, 06 Jul 2008 20:36:27 -0400 https://reprap.org/forum/read.php?4,13453,13987#msg-13987 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13987#msg-13987

Open your object's AoI file in AoI.

Find the view that you want to get the measurements for.

Pull down the Scene menu and select Grid.

Type in the grid resolution you want and click the "Show Grid" box and leaving the "Snap to Grid" box empty.

That will put a grid under the object. If you need to see through the object to see the grid, select the Scene menu again and from there select "Display Mode">Transparent. That will let you see grid lines through that view of your object.

If the grid is too coarse for the dimension you are trying to measure then increase the resolution until you get it.

If you are like I am and have more thumbs than fingers you may want to do some print screen/pastes to Paint and print them out. You can mark on those with a pencil rather than getting your screen greasy with fingerprints.

While AoI is pretty intuitive, a few hours spent futzing through the user's manual will reward the investment in time. 8-)]]> Forrest Higgs Reprappers Sun, 06 Jul 2008 19:21:01 -0400 https://reprap.org/forum/read.php?4,13453,13983#msg-13983 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13983#msg-13983 slade Reprappers Sun, 06 Jul 2008 18:42:40 -0400 https://reprap.org/forum/read.php?4,13453,13979#msg-13979 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13979#msg-13979 Forrest Higgs Reprappers Sun, 06 Jul 2008 18:18:32 -0400 https://reprap.org/forum/read.php?4,13453,13978#msg-13978 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13978#msg-13978

I'm just looking for a way to get started, and I need an extruder for that. I can then attach it to a CNC machine or just build a repstrap, but the extruder is the roadblock. buying the parts isn't really feasible, because the only place that sells them is in the UK and the shipping time would be as horrible as the exchange rate.

any help would be appreciated. I have enough tools that I could build the extruder out of delrin, aluminum, wood, etc., I just need a 2D dimensioned drawing (preferably pdf) of the parts or some other sort of help. I have AoI installed and it'll open the .aoi files from sourceforge, but I can't figure out how to get any dimensions. I have no idea how AoI works as of now, I'll try finding a tutorial.]]> slade Reprappers Sat, 05 Jul 2008 18:53:54 -0400 https://reprap.org/forum/read.php?4,13453,13867#msg-13867 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13867#msg-13867

PLEASE NOTE: The object files on here maybe "too new" and by that I mean that the fiels might have been just edit by one of the Core Reprappers and not be tested and not supported and may have wrong measurements...

That being said I have not really seen any of that but do realize that these files are not as neatly as organized as the zipped .stl files. However if you get Art of Illusion you can save them as non binary file format.... In my spare time I have started on making some of the soildworks files for the extruder. When I have it all modeled I will try and the the PDFs of the drawing posted somewhere.

I think what we should do to make things less confusing is to make sure that we add the date and Revision number of the object begin modeled on the drawings.
We can work on a Special BOM for the drawings later. So that people will know how many of each part to machine with out having to look it up else were and get confused.]]> ronanwarrior Reprappers Wed, 02 Jul 2008 20:02:29 -0400 https://reprap.org/forum/read.php?4,13453,13813#msg-13813 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13813#msg-13813 ronanwarrior Reprappers Wed, 02 Jul 2008 15:56:11 -0400 https://reprap.org/forum/read.php?4,13453,13808#msg-13808 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13808#msg-13808
I use pro/engineer daily and want to model everything and create drawings so I can build a reprap this summer. I have a few friends and engineers I know interested in building them too, so I'd leave at least one behind and take one off to college too.

however, the .stl files open in pro/engineer as a single feature id, meaning it's just a bunch of polygons and I can't get a dimension on anything. I use myriad occasionally at work and the .stl file opens in myriad, but I can't get a dimension there either (the dimensions it lets me display are, to say the least, crude and unhelpful).

I can get dimensions from the .dxf files like the McWire repstrap has. If I was able to get dimensions, I could model/draw everything, and make PDFs of the drawings.]]> slade Reprappers Wed, 02 Jul 2008 14:19:16 -0400 https://reprap.org/forum/read.php?4,13453,13485#msg-13485 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13485#msg-13485

I was hoping to machine most of my parts from scrap metal for the Cartesian Bot

Some of the bits (corner brackets spring to mind) have internal detail that will be hard to reproduce with milling. I'm not certain that you can just zap them all out of solid hunks of metal, thought I could be wrong.

The STL files for darwin were designed to be reprappable. As you don't have a reprap or rapid prototyper handy, you might be best off making a different sort of cartesian robot, such as the McWire.]]> Ru Reprappers Sun, 22 Jun 2008 09:59:19 -0400 https://reprap.org/forum/read.php?4,13453,13471#msg-13471 Re: Part dimensions and drawings https://reprap.org/forum/read.php?4,13453,13471#msg-13471 www.mediafire.com]
