Foldable M4 sherman tank print on ender 3 pro

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 STL 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 lowerrear 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.
