Articulated Dragon – 70 cm, Print-in-Place

Print it once, take it off the bed, and it wiggles. This dragon comes off the printer in one piece: a horned head, 26 linked body segments with back spikes, two pairs of clawed legs and a spade-tipped tail. Every joint prints in place. No supports, no assembly, no glue.

On the bed it is a compact spiral of 229 x 203 mm. Stretched out it is about 70 cm of dragon, long enough to drape over both arms. What it does - Curls up, snakes across the table, hangs from your hand. - 28 linked parts with hourglass pin joints in closed rings, designed for about ±50 degrees sideways per joint. - Designed with overhangs of 45 degrees or less, and it printed without supports. - Joint clearance in the model: 0.63 mm radial, 0.69 mm vertical, smallest gap 0.45 mm. Printing - Printed on a Bambu Lab X1 Carbon: 0.4 mm nozzle, 0.20 mm layers, matte white PLA, textured PEI plate, 2 walls, 15 % grid infill, brim auto, no supports. Slicer estimate 4 h 02 min, 117 g. - Footprint 229.2 x 203.1 mm plus a little room for the brim. Printed on a 256 x 256 mm bed; too large for 180 x 180 mm beds. - The 3MF is the project of that print. Check printer, material and plate settings for your machine. - Printed once at this size. Scaling it down also makes the joint gaps smaller. - Once it has cooled, work each joint gently. If one feels stuck, wiggle it loose instead of forcing it. Safety
