MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
The Buratinu is a smaller derivate of the Buratino which was designed by Bil in St. Petersburg.
Thank you Bil for the great design.
With its pointed nose I was optimistic that I would manage the CG problem, which is always tricky with printed planes.
The original has a wingspan of 1800 mm. I designed it for a wingspan of 1300 mm with slightly more sweep back.
Recommended Print Settings
The wings are designed to print using 0.5 mm width, 4 bottom and 4 top
layers, no infill, 1 perimeter only.
Should you print thinner walls, the perimeter of the upper side will not stick well enough
to the perimeter of the inner stiffening construction.
If you apply thicker walls, the perimeters will not come out continuously in one
The layers must build up as if you were printing in spiral vase mode. Only then you get a
smooth surface on the upper side.
If unsatisfied with the results, try out 0.49 or 0.48 width in your slices settings. It
depends whether you use Cura, Slic3r, S3D or what you have. I suggest you experiment with
some tests before printing the whole thing.
The second point is: Should you print lesser layer heights, the inner stiffening
construction will not connect well to the top and bottom layers. You will suffer a gap inbetween.

If you want to print the wingend with the winglet in one, you can now take the following part:
W6 incl. winglet
The base of the winglet is 1.5 mm thick.
This thickness must be completely filled with solid layer. E.g. 6 solid layers each 0.25 mm high.
Update 16th April 2019
fuselage front mc4 sp2 hd25
It has a motor bulkhead with 4° motor camber, 2° side pull and 4 mm holes with hole circle 25 mm.
Instead of the front pass hole there are thin bars for a stop rib for the battery.
Update 17th May 2019
Uploaded fuselage 1 mc4
It has already integrated 4° motor camber.
The hole pattern is rotated 90°.
