Friendly Dinosaur Mechanical Toy

thingiverse

A remix of my Friendly Dinosaur - now a mechanical toy with a bobbing head and tail (which are connected via an internal linkage). Use 1.75mm filament trimmed flush to connect the head/tail parts to the linkage bar. Everything (except the linkage bar) is in two halves. There's alignment pins to help with gluing everything together. Make sure you assembly everything and test before gluing! Assembly: Glue the head and tails parts together. Align the linkage bar up to the head and tail parts and insert the filament. Trim the filament flush - when everything is assembled it is held in place by the proximity of the body. Slot the head/linkage bar/tail assembly into one half of the body then fix the other half of the body. Printing: 7 main parts - left and right of body, head and tail, and the link bar. Print two body pins, one large head pin and three small pins. Use supports - there's a few small overhangs and incomplete bridges. You might prefer to block supports in the alignment holes to save having to dig them out of these! I use a brim to prevent warping - even a very small amount of warping looks bad when the halves are glued together. If you find the pins a bit tight/loose just re-scale them slightly in your slicer as appropriate. They're tiny pieces and will re-print quickly.
