And my 2nd pass at printing what Chris sent me is, I would say, successfull, as i raised the bed to just ticking the nozzle, so that the first layer put down was perhaps only .05mm high. Adhesion was excellent and I had to tap it sideways smartly with the handle of the putty knife suppied to get it to pop loose. The retainer flange looks ok, the belt fit nicely and I'll check my scrap box for a hiding hub half of the sprocket tomorrow. Now we go back to motorizing that clone BS-1. . . That is going to be a different critter entirely. The question there may need .2mm nozzles to generate the gears as the 2nd relay is quite short and probably best done with gears, belts need more room.
