someone should make a modular crane the has to be printed then assembled. You could use an arduino and some stepper motors and make working miniature crane!
yeah, I'll probably do a set of end caps for use with threaded rods since they are so much better structurally, but I don't for see this being a big problem for a reprap scale, print heads are pretty light, I am more worried about plastic creep. I think that I may be able to engineer it creep resistant.
Threw it under LGPL because it sounds pretty. is that alright or do you have some other preference. I'd rather not go full public domain because it is source code.

Did you print it?
That is used to tension it?
Are the connections stable enough?
How much lateral force did you meassure with what bending compared to what weight of the pillar?
I'm afraid that I simply don't have a reprap nor any money. I will need to save up my Christmases and birthdays if I am to afford one. son no I didn't print it and frankly the inability to see the results of my work are discouraging, I rarely work on this despite the fact that given the amount of free time I have I could probably make a full plastic Cartesian bot in months.
Forest higgs is working on a similar project, it should show show what this kind of design is capable of although he uses a far superior (and sadly using exotic parts that can't be printed) post tensioning system. this allows him to have a much stronger piece then this can ever be but due to the s
hape without the post tensioning I am fairly sure that his is structurally weaker.

he claims the pins are not great but when prompted hasn't suggested any alternatives.
as for tension I have a ratcheting tensioning beam
that should be able to use any string. I think flat shoelaces would be best. the idea is you put it through the hole at the top of the pillar around the column on the other pillar then tie it to the tensioning rod. you can now simply turn the rod and it will tighten. like that myth busters episode w
here they try and break prison bars by turning a beam and a pee soaked blanket.
Interesting. I don't see threaded rod as too exotic not to use it though :)
Is the licence intentionally restrictive?
