About this 3D model
this is a fun model that is super satisfying to make stop, before you assemble add a piece of TPU in the hole on the top of the tank body so that when it and the part that rotates come in to contact it makes a satisfying “click”every time you tern it! see pics I haven't tested these on my model but I think they will work? if you can just use a major brick brand:) wheels https://www.thingiverse.com/thing:3868562 wheel mounting pins https://www.thingiverse.com/thing:2225043
