Explanation : The tractor was modeled as a 3D solid puzzle. Added a wagon that can be connected to the tractor. The thickness is 2.8mm, and if the assembly is not good, try to join after trimming the joint. Multiple parts of the same shape should be printed (B:2, C:6, E:5, J:2, K:2, L:2, T:32, U: 6, V:6, W:2, X:2, Y:8, Z:8, ZA:2, ZD:2, ZE:2, ZI:2, ZJ: 2 You can also download this file from the link : Many other 3Dprinting files are in the "3DSangSangPortal".
