Tin Toys have not been able to make the picture of the packaging box properly due to the limitation of the production technology. The Tin toy remake project is going beyond these limits with 3D printing and trying to make the most of the original ideas not just toy.

Foldable Robot BR is the remake of the most popular Tin toy robot, but it has been postponed because of the spring above the head (called a radar) and is now complete. We've done a lot of work to adjust the size, spacing, and thickness of the head radar (spring) so that it can be print without support. I designed the mechanism of the chest which was pictured in Tin toy with the structure that the gear wheel that was bitten and rotated. When you insert the key into the side, these gears rotate, and the key is the same as that used in other foldable robots. Move the left button of the gear wheel to the left or right to move the needle upwards.

Its arms are pulled outward and aligned. The legs can move back and forth. You can express various postures as its arms and legs move.

Three things to watch out for 3D printing this design.
The first is the thin strings. These strings flow down the melted filament as the nozzle moves between the object and the object. When these occur, the gap between the parts is interrupted and the arms, legs, and head can not move. To reduce or eliminate this, you need to increase Retraction.

The second is Elephant food phenomenon. This indicates that the first layer is spread out slightly wider than the actual data. This is not good for printing a foldable robot because it fills the gaps in the first layer. In order to avoid this phenomenon, please make sure the gap between the build bed and the nozzle is correct or use the Raft.

The third is build-plate adhesion. FDM 3D printers are susceptible to dropping from the Build bed during printing because of their strong vibration and shaking motion. In particular, the arm of the foldable robot falls well on the build bed. Raft is recommended to avoid this.

    Hi! Awesome design. Really well made in my opinion. Just one thing. It would be awesome if you could offer a small free stl for testing each one's printer tolerances. With your settings but in my machine and with my filament, the robot ended with welded joints.

    We have couple of free models. Especially foldable android robot will be helpful for testing print our foldable designs. https://fab365.net/items/139 Thanks~

    Nice model. Not a big fan of having the Fab365 on the outside. :(
