Z Axis Extender Kit for Makerbot Cupcake
Description
This was inspired by thingiverse.com/thing:4261 and the pulley mounted crank from that settup works great with this.
I've added .obj files for those who want to stretch things a bit more...

I'm having an issue generating the GCode for the Z_Extension_FBUpper, it generates with skeingforge 31, but not 35, any ideas?
Okay it's all done and moving smoothly up to 194mm now.. What to print though? :)
I'm printing out large sections that I will be glued together to make a model of a car body panel. So these extenders help save time and reduce variance in the final piece. Gluing hundreds of small cupcake size pieces are a headache and increase dimensional errors due to gluing and flawed varied adjustments involved. Ideally, it would be better to have one gigantic room size printer to print out the panel in one job. So these extenders at least tends towards that direction.

It's also nice to scale up some of the vase designs on Thingiverse.
I'm totally going to do this.. I love making tall prints! What about those winged-bolt things keeping the top riser bits in place, what are those called if I go to a hardware store to pick some up?
out of curiousity... how many copies of each do you have to make? Is 4 the magic number?
Wow, this is simply amazing!
has anyone tried this yet with the automated build platform? Should These files be stretched more for it?
LOL.. awesome...
sooo. how do this do for the wobble.?
Actually not too bad on the wobble. I have mendel-style X and Y axes which help. Depends what you print. Twice the print height=twice the possibility of mystery X-axis shifts. Also the nozzle bumping into excess material at the top has twice the leverage to mess things up.
Funny enough, smaller prints are much smoother now. This is because two of my Z rods are bowed in the middle and the towers make the print start at the previously unused bottom of the rods which are much less wobbly.

how on earth did you bolt in all 4 corners of all 4 extenders (with the bearing mounted in the top) this is extremely challenging to install
this is one of the great upgrades that is also an exercise in zen makerbot assembly and disassembly. :)
Do you mean the extender bases? I used a long hex key and a Thing from Thingiverse called a Cupcake tool or something like that. Still, lots of dropped nuts...
