As soon as I printed the fixed version I'll try to actually plot something with a pencil.

Sorry for the delay, I have about 50 earrings printed that need to be photographed, uploaded and posted! (Unless you care for the raw SKP/STL uploads...)
Stay tuned for a rotating washing machine, a spinning table saw and much, much more...

After thinking about a 3D Printer earring a lot (and seeing http://youtube.com/watch?v=hfAFWzh2VEM ) I created this little plotter earring.
Of course my plotter is not nearly as sophisticated, but it works (as in: moves).
I quickly whipped it up yesterday and I had to cope with the printer/size limitations, though it can probably be scaled down a little bit if adjusting the tolerances/clearances.

Pen Up/Down "Switch"

Turn-Dials with segment digits
Earring loop :-)

Placing the gear-rods in the center would make it less wobbly, but I would have to make it thicker.

(render-pictures are from the older version as well)


This is a untested revision, but it should print fine.
PLEASE run it through a repair tool such as Netfabb/cloud Netfabb as in the project file everything is still not unified and may cause terrible printing errors.

The older file had some issues (loose rods which I fixed by gluing scrap parts to the frame) and cutting/sanding off everything that did not fit.

To all followers: Sorry for spamming your dashboard with the amount of updates, but I have re-printed it and included all changes now. Make sure to print version 5h; The smaller version (x0.7) is still experimental. Otherwise it works quite well now with a minimum of glue and sanding/cleaning required ;-) Some minor changes are untested (spacing on the frame for the rods, switch-shape and platform/grabber changes) but they correct what was wrong with the last tested version...

(on a UP with 4 layers raft, 0.2mm/fine, 30° & wide support material, 2.44hrs)

Note: The little cubes are there to increase the adhesion on my UP PP3DP with raft. The whole thing could be printed raftless and with minimal support (I used the 30° support angle setting), but some overhangs where necessary. I included a picture where you can see how to print with minimal raft, though if the rods point upwards they are less durable!

Man, these things are ridiculously cool. It boggles my brain how you come up with all these designs!

Thanks! :-) Too many ideas, too many doodles :-)
