Design Iteration

One of the nice things about having a 3D printer is that it makes it really easy to iterate designs. I'm working on a new design for the configurable game controller. This version will have a socket for an input device and a bar-graph above each socket. I think I've found a design that sort of works, now to make up a panel. 

Oh, and one 3D printing top tip from Rob. Don't use oil on the sliding components. I thought this was a good plan, adding some "3 in 1" until the print head was moving really freely. What I'd forgotten though is that oil is sticky, and attracts dust. So when I fired up Una to print these prototypes she became very upset and pretty much locked up as all the sticky dust gummed everything up. Fortunately, after a good clean-up she's now working just fine.
