What kind of filament is this for. I tried putting some MBI 3 mm ABS Natural White filament on this thing and all it wanted to do was unwind. Is there some other filament out there that comes more tightly coiled or something?
I guess your t-slots are a lot bigger than mine. I couldn't turn them at all.
I held the rod steady while turning the nuts.

Instructions
* 18 ea. 110mm threaded rod (M4 or 10-24 will work) (green on diagrams)
* 6 ea. 160mm threaded rod (blue on diagrams)
* 3 ea. 194mm threaded rod (yellow on diagrams)
* nuts
The images show the assembly sequence. The spindle should turn freely on the support.
Both printed_spindle_assembly.stl and printed_spindle_assembly.pdf provide rotatable and zoomable views of the entire assembly. The PDF also supports turning on and off parts of the assembly.
printed_spindle.stp contains the whole design (Alibre Design 11.2)
printed_spindle_step_ap_214.stp hopefully is importable by older versions.

I have been building this and mine isn't turning out so well. How did you guys get your base triangles tpgether? I mean, the first two rods of each triangle goes together fine, but that third bar is impossible! If you start with the third rod screwed in to one corner, when you screw it into the other corner, you just end up unscrewing the first corner. This has been a nightmare and my base looks all messed up.
I ended up drilling far past the t-slot, to make room so I can screw into the triangle on one side further, just so when I screw into the other, I am not totally unscrewing the first corner. This has left me screwed and my base askew.
How did you guys manage to build these triangles?
Looks like much sturdier. I have been fighting the other one falling apart.
Is there a way to save the Alibre file in verison agnostic? I have version 11.1 and I can not load the stp file.
Maybe export as .igs or 214-stp file? I wonder what could easily be used by google or blender?
Try printed_spindle_step_ap_214.stp . Unfortunately that export option stripped out all of the sketches and constraints.
It's so nice to see a full 11 implementations of this type of accessory (at http://www.thingiverse.com/tag..., many of which are building on each other and inspiring each other to provide this functionality while giving users several options.
This one seems really solid :)
Not sure how familiar you are K'Nex which is a construction set aimed at children but from the thumbnails it reminds me of it. I wonder if it is possible to print K'Nex compatible parts on the MakerBot?
I remember seeing adverts for K'Nex a long time ago but never looked at them closely. Lego-compatible parts are on Thingiverse, it'd be cool if someone also did K'Nex :)
Am I the only oner to think there's a resemblance between the support framer and a Mendel frame? Might be worth experimenting...
Vik :v)
Well, I guess when it comes to simple, stable, rigid geometric shapes, a triangle is likely the first thing what comes to mind...
