About this 3D model

Needs a properly tuned printer for the tight clearance. Before printing full submarine printing clearnance test is advised. Print both parts, add bolt to front of submarine, lastly add rubberbands. For best spin, try adding more rubberbands for a looser chain of rubberbands. For more of mt 3D models, visit my makerworld profile: https://makerworld.com/en/@Jallim
