GOODesign is a design studio established in Seoul, Korea by a representative who has been active in product design and 3D CG field for 20 years. As a design company that pursues a reasonable and differentiated digital design, it has always presented a new direction through working with clients such as Hyundai Motor, Siemens Korea and beiersdorf.   This time, we have put out the life product for 3D printing by utilizing various technique design based on the shape of the Class-A surface. These products are especially the result of deep research on the 3D printing dominant shape that can not be mass-produced using a mold.

It is the American Sherman tank that received many requests from people while designing the WWII tank series with a folding structure. The reason it was put off despite many requests is that the Sherman Tank's wheels and track structures are unique and complex. Moreover, the size of the Sherman tank itself was so small that it was very difficult to make this complex structure by folding. So we spent a lot of time designing. But I did it in the end!

The folding process is as follows:
1. Insert the front part of the tank body.
2. Put the side part on the top, and then the front part.
3. Raise the lower-rear part and rotate the protrusion to insert it into the front part.
4. Put the 6 wheels on the body.
5. Fit the front cog wheels and then the rear wheels.
6. Connect tracks to make two pairs.
7. Put the tracks around the wheel, then connect the start and end of the tracks.
8. Slide the cannon through the hole in the cannon part and then insert it into the turret.
9. Glue the two parts in front of the body.

This design may be difficult to print due to its small size and many sophisticated parts. Therefore, it is strongly recommended to print large.
If the wheel suspension is loose, attach it with adhesive. When using glue, be careful not to stick to the wheels.
Track rolls better and better with a lot of movement.

    Dear Sir:

    Your printing instruction never mentioned the setting of Retraction on the PruSlicer,
    Should I special set the Retraction distance on PruSlicer ? My printer is PRUSA i3 MK3S.


    Thanks.

    Peter

    @peterwu280 Have you tried the slicer setting file for prusa provided by Fab365?

    Tank comes out pretty well, without resizing. The tracks however, come out stiff, and not movable. Any idea how to adjust slicer so they become flexible?
    I use Simplify3D and Wanhao D6
    PS: Tracks for Tiger, came out fine.

    Raft는 안쓰는게 좋을 것 같아요
    Raft 쓰고 뽑았더니 다른데는 잘떨어져도, 작은 바퀴들이 모두 축이 부러져버려요 ㅜㅜ

    Cura 쓰시나요? Air gap 세팅을 높이면 잘 떨어집니다. Raft가 안 떨어져서 그런 것인데, Air gap을 늘리면 잘 떨어집니다.
    Do you use Cura? If you increase the air gap setting, it will fall well. It's because the raft doesn't fall, but if you increase the air gap, raft falls well.
