Revised Fully Printable Eggbot by Glasswalker

Last crawled date: 3 years ago

This is a fully printable eggbot, which was inspired by the original Eggbot as well as the other designs by Zaggo and Berserker.
I designed this one to be complete, and fully printable. And easily assembled. Also all parts are no larger than 100mm in any direction so should be printable on any 3D Printer out there. Lastly I wanted to keep the amount of plastic used to a minimum where possible.
It's intended to be printed in PLA on my Ultimaker.
It's unfinished in that I haven't printed it myself to test it. Normally I don't release things until they are "done" but since Easter is coming up fast, I thought I better get this one out there so hopefully some others can build one in time. I'm hoping to make mine this weekend, and will post pics once it's assembled.
It's intended to be used with the spherebot electronics and firmware. http://www.thingiverse.com/thing:7656
Hope you enjoy!
EDIT April 2 2012:
I've refined some of the parts. Updated STLs are uploaded. The Egg cup parts didn't work out as planned, replaced them with suction cup based ones. Also I strengthened and thickened up the Back Plate part as it was a little flimsy (still works in it's original form, as I left it on mine, but I figured it could use some strengthening for general use).
EDIT April 4 2012:
Ok another minor revision to a few parts. I've uploaded the new designs now. Also here are some pics of the finished build. I'm still just wrapping up the electronics. The changes I made were shortening the egg cup holders to allow for a larger egg to fit, and I had to adjust the arm pivot to allow the motor shaft to protrude through it. You will need washers on those screws now but it will allow a better depth adjustment for the pen to allow it to center up nicely on the egg (keeping the image from skewing when you print it).

EDIT March 21 2016
I know it's been a long time, and this design is apparently still popular, so I'm planning on doing a full refresh of this design. I'll be posting it sometime in the near future. I'll be completely overhauling it for better stability, printability, and I intend to make it fully Parametric for easier tuning/customization.
Also quick shameless plug, anyone looking for anything to be printed, please check out my 3D Hub at: https://www.3dhubs.com/ottawa/hubs/glasswalker
Thanks!
