I'm in the same boat as crispyfry, unable to buy the Hadron parts to feed my obsession, but unlike crispyfry, I have no 3D printer to make the parts I need. I've spent probably enough time to build an ORD Bot, just trying to source the parts, and I still have a decent list of unobtanium that I'll be fabricating from aluminum on my milling machine (albeit not as pretty as the professionally built Hadron parts).
While I completely understand printing Hadron parts from plastic to get the project underway and wish I could do that, I also concur with crispyfry on the entire silliness of the 3D printing community clinging to the concept of printing the printer parts as if it's some sort of religion. It was a clever idea, but it got the 3D printing technology off into left field for a couple of years IMO. I wanted a 3D printer back then, but I recognized the inherent problems in the designs, but with the advent of the ORD Bot and others using similar rigid frames with low parts count, I'm now buying in myself. I guess if I was a dude-and-a-half like Bart, I could have designed my own new and improved version, but, hey... I've been busy!
When Hadron parts are readily available and consistently sourced and there are 20 ORD-ish 3D printers on eBay at any given time for $150 above the kit cost, then 3D printing will REALLY take off.
And to those who still dream of self replicating robots... the first step is low parts count with quick and easy assembly.
