When I heard of the RepRap project all those years back, I was totally awed by the concept of a self-replicating 3D printer. Then I saw the Darwin and then the Mendel… It always bothered me that most of the parts that I saw in these printers weren’t printed, but metal or wood. Even now, the most popular RepRap variants are very obviously made up of materials that are not printable. The closest ideal that I’ve seen is this incredible contraption: a fully printed Makerbot Cupcake.
Since then, there hasn’t really been much movement in the space… At least none that I’ve seen. So, I present:
Y Block Construction Set
This construction set was made to be used as a printable frame that gets quite rigid when you screw them down together with M3 bolts. I’m hoping that it’s rigid enough to support 3D printing. It isn’t quite ready to be RepRap just yet. The mounts for the electronics and the X,Y,Z printing axes still need to be made. But, now you can make a little box:
