rbandrewsThese are Naef blocks. They're a construction toy made by Kurt Naef in 1955. His are handmade from wood in Switzerland. Mine are Makerbot-made from PLA filament in Texas. Which is probably why his cost $160 for a set of 16 and mine cost about 12 cents each.
They're pretty fun to play with. They came out all right too. I may start messing with ABS again this weekend, I haven't decided. I think I can probably run it successfully through the Makerbot now. I've discovered that running the Makerbot slower helps quality a lot: when it tries to infill very narrow walls, it essentially just vibrates the print head, so it's just barfing out a blobby line of plastic. This is partly because the table it's on is wobbly, partly because the print head is massive: two extruders, two heating blocks, two fans, that don't weigh an ounce.
Speed helps some, another idea I'm toying around with will probably help more.
Bonus shot of Cassie's book in Barnes & Noble!
