I’m trying to get the steps needed to get this fuselage shape drawn documented. This will be the part that the undercarriage has to connect to.

Insert the image
Scale it to the correct dimensions
Shift it to the 0,0 origin (just for easiness)
Draw a B-Spline curve
Do another and shift it backwards 190mm
Select curved shapes, identify the 2 lines, and voila!

The back curve should have a sharper corner, I’ll work on that. Next step is adding the leg and try the fillet parts…

And we have a leg. Next the hardest part yet, a smooth transition between leg and fuselage.

As always I manage to find the bugs.. Just do quick test for the PT-17 legwarmers.

The design was easy, so what can go wrong. I have been using Simplify3D for a long time, always did what I asked it to do. Until now. I asked it to print this very simple structure, but for reasons only known to it’s inner self, it prints the outline and infill and ignores the internal tube. Ok, well if you don’t want to play, there’s always Cura. And lo and behold, Cura plays nice. Ah well, so I let Cura do the slicing and upload the result directly to the Octopi, and all is well. Pity this is, because I really like(d) Simplify for other reasons. I guess I’ll have to dive into the interwebs to find out the why..

Meanwhile, my Printslave is doing it’s bestest.

important bits of code are there, so that I don’t loose them!
..always fun to let others see glimpses of the workshop 😉

yeah, I need to add some lights at the back of the camera, now where did I put those leds again?

oh, yes the link to the original code:
