Best way to import and combine meshes from Blender

[TrippyLighting]

I've imported several things that I've initially modeled in Blender ino Fusion 360 (obj) and converted these into T-Spline models.

However in his case I want to import three differnet objets shown in the screenshot (from Blender) into Fusion 360 combine them and add mechanical features for assembly. Ultimately I want to create 2 objects  and export stl files from these to be 3D printed at Shapeways out of their Strong and Flexible nylon plastic.

What is the best way to combine these objects ?

I've removed the subdivision modifier from Blender and exported the control meshes as .obj files. then I imported these into Fusion 360 and converted into three separate T-Splines. Is this the correct approach ? What do I do then ?

BTW I run Fusion on a mid 2010 27" iMac with core I7, 12GB RAM and 1GB video memory and Fusion has been chewing pretty hard on the tube object for a while (10+ minutes) when converting it into a T-Spline. It also warned about graphics memory being low and turing of some features. Only antialiasing was actually left 😉

The screenshot below is from Blender's viewport:

It's difficult to tell what is going on from the screenshot. Can you post a screenshot of the obj freshly imported? Is that a bitmap texture or 3D geometry in the model? 

Thanks,

The image is what I want to end up with. No bitmap texture, all geometry 😉

in Blender they are just intersecting subdivision surfaces without any real interaction.

I have figured out how to join these separate T-Splines.
