FlexiDinos FINAL VERSION: Ginko the flexi Brachiosaurus print in place articulated dinosaur

Size matters. 

(See the edit below for instructions on printing and finishing)

This is a re-upload of Ginko the flexi Brachiosaurus. I redesigned some details of the model for improved printability, so there should be better results coming out of your printer. I chose to remove the hinges to have a free version which is not as cool as this one. 

Say hello to my latest creation, the Brachiosaurus. Made to feed Tessa or to keep Günther, Theobald and Bertha company, this model will trample your mind. 

As usual I had a drawing and my club member @BenKenobi won and came up with this lovely name regarding the diet of this giant. Everybody else: If you also want the chance to give one of my creations a name, why don't you sign up for my club?

Heres some tech specs for all you nerds out there: The main joints work as usual, they are no longer interlocked, which gives me a lot more freedom in the design process. If you want to know the details, check out Bertha, I explain it there.

The main feature is the leg and jaw joints. The gimmick here is that they are asymmetrical, so you can start with just one point on the bottom and use the counterpart of the joint as a support. This is a new take on the whole vertical hinge mechanism I introduced on the jaw of the Tessa model, and it works much better than I expected. So I'll definitely be using this trick a lot more in the future. It may be a bit tricky to get the parts to separate, see below if you have trouble getting them loose.

Special thanks to Club Member @DARK for helping me print the last prototypes, as I short-circuited my printer (don't try to fix a ground wire mid-print with a pair of tweezers) and currently have no time to fix it, although the spare part is already here. First world problems. 

Edit: A new version is now online (v84). I fixed the connection between the joints and their counterparts as the cones tended to jump out in the middle of the print. I also rounded the front and back edges of the legs as they broke in some cases (thanks for pointing this out @Torsten_523515).

I am printing the prototypes on a Prusa i3 MK 3 with a .6 nozzle and they are coming out fine. I'll upload the gcode here as well. The jaw and leg joints don't move when you take it off the bed. This is intentional and they need to be loosened.

A quick guide on how to do this after you print the model: They stick together because they are printed with a small connection between the cones. This is because otherwise they can fall out in the middle of printing and mess it up. So you'll have to separate them. Don't be too fussy on the legs, they are sturdy and should be able to withstand some force (it's a dinosaur). 

Take a pair of pliers and some cloth to protect the surface and twist it until it snaps loose. Make sure you grab it as close to the joint as possible, otherwise the torque can break the legs.

The jaw on the other hand is a different case. With my settings, it tends to come loose with less force because there is also a smaller surface to grab onto on the counterpart. If you must use force, be sure to apply it to the base of the joint, as the leverage could break the jaw joint.

I can't stress this enough, so I'm going to write it down here: FlexiDinos are in no way suitable for small children. Parts can break off and leave sharp edges, so make sure your children are old enough to know what they're doing before letting them play with FlexiDinos!
