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, 30Â° & 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 30Â° 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!
