I also made some spools for jumper wire that fit in my trusty electronics tackle boxes:

I've also been working on a set of parts that'll attach to a standard Cupcake CNC to add fume hood functionality for a fellow Makerbot operator.  It's not done yet, but the parts I have done make it look like a little oven, which I think is pretty awesome:

I've also been working on the CNC router at CCCKC, which has had a few successful test cuts and should help me finish a few long-running projects I've had on the back burner.  Check out this CCCKC blog post for video and some more info.

Lastly, I've been working on my self replicating CNC project again.  I've decided to make this project even more ambitious and I've acquired most of the hardware that I think I'll need to finish it up, or at least get it off it's feet.  I'm also learning OpenSCAD and doing all my initial design and prototyping in OpenSCAD.  I'm going to try and use OpenSCAD to model all the milled components in 3D and then use OpenSCAD's 2D rendering capabilities to generate the DXF files that will eventually be used to generate tool paths to actually mill the parts.  I'm trying to make the design very parametric and well organized so it'll be easy for me to tweak and easy for others to modify use the parts they have on hand or make new  derivatives.  The CCCKCCNC being up should help prototyping as well.

I saw this awesome MakerBot accessory over at Thingiverse and had to make one.  This thing glides nice and smoothly and looks freak'n sweet.  I also managed to find a place in town that I can get roller bearings from for cheap in the process, by the hundreds if needed!  This spindle is headed down to the space for use with our (hopefully) soon to arrive MakerBot.  I made a few minor changes to the design and will probably make a few more when I make one for my personal bot.  One issue I encountered that I hadn't even noticed till I dropped this baby off at the space is the fact that the separation between the two outside plates had grown as I spooled the plastic onto the roll and many of the bridging pieces weren't making contact with the second plate.  I'll have to try and address this problem as well as the  fact that the filament likes to unravel when there's no tension on it in the next one.  Here's some additional pics of the assembly of the bearing clamps if you want to make your own:
