  1. So, based on other comments I've seen on this forum, I'd say your outer diameters are about as good as you're going to get.  I mean less than 1% error ( actually 0.7% ) is pretty acceptable in my world.  Likewise, the height error is only 0.3%.  Again, pretty much an acceptable variance in my world.

     

    The I.D. is somewhat adjustable using the "Horizontal Expansion" setting.  This has been discussed elsewhere on this forum.

     

    I'm sure someone will more knowledge than I will jump in here at some point.

     

     

  2. Welcome back from your world travels.  Hope you at least did a little sight seeing and relaxing . . .

     

    Thanks for the update Thomas.  Cura 3.5 is so "buggy" I have un-installed it and continue to use 3.4.1.  Your plugin V0.5.5 works just fine in Cura 3.4.1.  What is the new version number of your plugin, and what improvements were made?

     

    Cura 3.5 was not ready for prime time IMHO.  Pretty disappointing. ☹️

  3. SolidWorks plugin no longer works with Cura 3.5

    Fails both from inside Cura 3.5 when opening a SolidWorks file from the Cura File menu as well as from inside SolidWorks using the Cura macro.  Worked fine in Cura 3.4.1

  4. I must say Giovanni you peaked my interest with your cube measurements.  I print most objects much larger than your cube but sometimes smaller threaded objects (neck finish of bottle) where a cap must be screwed on, and I never see the kind of variation you have described.  Here are photos of a cube I printed that is .875"  (7/8") on a side.  I chose that size arbitrarily, but it is close to your cube.  The Z is only off target by .0035" (0.09mm), and while the X & Y are some .012 (0.3mm) larger than the target, they are within .0015" (0.04mm) of each other.

    Settings:

    .4 Nozzle, .2 Layer, Print speeds, outer wall 20mm/s, inner wall 30mm/s, 15% infill (Lines) Wall Jerk 3mm/s, travel speed 125, Print & Travel Acceleration Speeds 2000mm/s.  Generic PLA at 205°

     

    As you can see I print pretty slow.  I find accuracy is quite dependent on speed

     

    I don't think you can expect results much better than these figures from an FDM printer.  Hope this gives you some insight into the capabilities of the UM3.

     

  5. I was not aware that the project was designed to be a printing challenge.  Also I had no idea the parts could not be separated, for post printing assembly, for some unapparent reason.  I was thinking more along the lines of good DfAM.  While I have a UM3 Ext, and I assume you do as well, not everyone has the ability to print with dis-solvable PVA supports.  Printing this part without that ability would be a real mess IMHO.

    As smartavionics said earlier:   3d printing, it's a tradeoff

    Anyway, just my 2¢ worth . . .

  6. I would print the part in 3 pieces.  Top and bottom plates with a hole the diameter of the connector rod, and the Rod itself.  Press fit or glue the assembly.  Might need to use a brim on the connector rod.  Print the two plates first and get the actual hole diameter that the printer produces and then experiment by printing a short section of the rod until you get a good fit.  Then print the whole rod.  No support material required.
