Using OpenJSCAD to print a house (2/N): Small Print!

I advanced the code significantly:

https://github.com/sunnywiz/housejscad/releases/tag/Post2

  • I introduced a “TwoD” class to take the pain out of working in the 2-D character space.
  • I traced out my house’s 4th floor plan to a text file, so I’m dealing with the real thing now rather than test data.
  • I got my 3D printer back up and running – didn’t need any re-calibration after 6 months of no-use.  I had to go read the powerpoint of the presentation I gave a while back to re-remember what to do.
  • The result is this print, which is 1:72 scale, and took about 4 hours (1 failed print included):

Its in two pieces so that:

  • I don’t have to print support structures for the doorways and windows
  • We see things at eye-level, or about 5.5 feet; the model is 8 feet; this makes the model feel overly tall.  With a removable section a little lower, this becomes more “playable”. (I need to move the cut line up though to be at about 5 feet.  Or, move the windows down a bit)

I’ll do a full “How To” video at some point in the future – I’m not quite done yet.  There’s some bleeding edge stuff in the “cuts” branch at the moment:

  • I’ve learned how to do real drag-and-drop libraries, in a separate file, which will work with OpenJSCAD
  • I’m working on a cutting algorithm that will let me cut with tabs.  Its workable now, but needs some fine tuning on gap distances.
  • We’ve (wife and I) decided to do the final print in 1:48 scale – there’s a lot of toy furniture out there available at that scale.  And it will be printed in white.

More to follow at some point.
