Hmm the stud looks a bit wimpy to fit a sleeve.

I've been looking at the ormerod for a few weeks now, the few vids showing it on YouTube seem to be pretty good, self replicating, the metal parts seem pretty standard stuff too. Had a chat with our son today and have agreed to go halves on one, should be here tomorrow.

Apart from the troubles with my trial setup, the base machine is destined to be a plasma cutter next week and once you start cutting steel, it gets messy very quickly, not good for 3d stuff. I was just mucking about with the the 3d while waiting the couple of weeks I had to for the plasma cutter to arrive :)
