3d Modeling every component was by far one of the most time-consuming things this project had to offer. Having to trace the handle and making it the size of hand you want is definitely a challenge. When tracing the handle make sure you go back on the fusion timeline and fix all of your errors because it will cause lots of problems. For exporting make sure it is exported as a STL. You can do OBJ but you will have to upscale it by 1000 because it will downscale the model always.
