Re: CAD models for MK3 parts


FYI, all the files for the metal frame parts are up now: https://github.com/prusa3d/Original-Prusa-i3/tree/MK3/Frame

That's good, I told CS that it was missing and they told the upper powers that be.

BTW, i am working on a SolidWorks version of the MK3, and I will probably post the STEP files on thingiverse or Github, if I am allowed to do that.
since the OpenSCAD files have the values, I should be able to easily reverse engineer them!

Neat, I had been thinking about doing the same thing. I would stick with Github and make it a fork, just make sure to include the same license https://github.com/prusa3d/Prusa-Firmware/blob/MK3/LICENSE .

Re: CAD models for MK3 parts

I have converted most of the printed parts into STEP format and posted them on Github.
You can view them here: https://github.com/jzkmath/Original-Prusa-i3/tree/MK3/Printed-Parts

Unfortunately, some of the OpenSCAD files I was unable to convert using freeCAD. If someone wants to attempt to fix them that would be much appreciated.
Also, two of the OpenSCAD files are actually incorrect, ('x-end-idler.scad' and 'x-end-motor.scad') I have posted a picture of what I mean, so PR might want to fix that.
- Einsy-base.scad
- x-carriage.scad
- x-end-idler.scad (broken)
- x-end-motor.scad (broken)
- z-axis-top.scad

I am working on a SolidWorks Assembly, so I will post a copy of that in "pack and go" format once I finish it.

Actually this post was about the non-printable parts. But as we are here...
What a mess some SCAD and STL files are. Currently (when I feel like it) I am redrawing the extruder body natively in Alibre Design, based on the an imported STEP geometry. Not quite there yet:

Re: CAD models for MK3 parts

Looks Great Guys!

I would want the .step files as well to use in Solidworks. GrabCAD is a great source for Solidworks files and more. STL files are not used to design from or modify.

Need to do a Solidworks Pack & Go zip file or file ZIP of all the .step parts so the can get one BIG single download instead of all separate Github files taking hours.

Cheers,
BDB1

Cannot load a file but just code for the DXF....not good.

Need a .dxf intact file to use.

I made a fork of the STEP files into one single folder that you can download.
I have most of the SolidWorks design finished, by the way, I will put it on both Github and GrabCAD when I am finished with it...

Great work and thanks for publishing the STEP files 😀 - Be making a Fusion 360 assembly in the near future...
Olso in the habit of modifying parts 😉

Have a look at my models on Printables.com 😉

no problem, I am almost done with it.

Just wondering if anyone can create a STEP file of these parts:
- Einsey-base
- x-end-idler
- x-end-motor
- the MK52 heated bed (or a DXF would work too!)

If someone can help me get these files, that will finish this off, and I can post a full SolidWorks Assembly, and STEP file version, which I will post on github and grabCAD.

I have a screenshot of my progress so far.

Thanks Area51, now I remember why I decided to get the Prusa and not the Makergear...

Had the same problem with SCAD files in FreeCAD, un-comment the version number helped to convert them!
Just the Einsy-base is a bit.h

Yes, removing the version number helped for the x-end-motor, but not for the x-end-idler.
I somewhere read that reducing face numbers and making them divisible by 8 might help... so $fn=24 or 32 might be worth a try.

Re: CAD models for MK3 parts

Can't you just use the STl Files ? or is there more information in the parts going SCAD -> STEP -> SWX instead of going STL -> SWX (or STL -> SWX -> STEP ->
SWX)?

attached the EInsy Base from STL

Re: CAD models for MK3 parts

STL files contain an triangulated mesh which is mostly worthless for further CAD work. In Alibre, I can just view those, but not connect constraints for assemblies or project geometries. Alibre inherited an STL importer from Geomagic, which sometimes works and at least results in selectable geometries. For most parts however, you need at least step or iges. Freecad can load SCAD (openscad is installed) and export step, but some models like the x-end-idler seem to be... corrupted? difficult? I saw the mid-tier Solidworks license ($5.5k) also has an STL importer IIRC.

BTW attachements of anything else than jpg images don't seem to work here.

... i know about the triangles... I use Solidworks Professionell at work.

attached the Einsy zip. Camouflaged as a jpg....

EDIT: i hate this forum softeware.... can't i uplaod anything ? ah... at least a screenshot of the Einsy Base

Cannot load a file but just code for the DXF....not good.

Need a .dxf intact file to use.

The DXF's are intact, you should try downloading the repo as a zip, GitHub makes it a little weird to download individual files.

Try this link: https://github.com/prusa3d/Original-Prusa-i3/archive/MK3.zip

Einsy-base1.JPG

Can you PM me the SLDPRT file of the Einsy Base? (send me a dropbox link)

I have converted both the x-end-idler and x-end-motor to STEP. The reason it wasn't originally working was that I had the bearing.scad file in another folder, so the parent modules all failed...
All my STEP Files as of this point are here: https://github.com/jzkmath/Original-Prusa-i3/tree/MK3

If I get the Einsy Base, then I will have a completed Assembly by the end of today.
