VW Air-Cooled Flat-4 Engine Assembly

Hi all! This is my first model in Makerworld and I want everybody to enjoy my models freely :) Tolerance is optimized, but if you can adjust the print settings or optimize the tolerance or designs, please do. I am more than welcome! This model is VW air-cooled flat-4 engine Assembly, the famous VW engine. I modeled it in CATIA and SOLIDWORKS, and you are free to check out my SW files. Some files have error, it is because I ruined everything to optimize for 3D printing…. Just refer to my files if you need it. I think you won't need the assembly instruction since this is quite a simple model. I am still learning, so my model isn't perfect. Please suggest me if you find anything that I can revise or any suggestions on print settings are welcome! Good luck with your priniting!! Boost MeThank You!!
