hello and thanks in advance, i am trying to print a nut that goes on the choke of a carburator for a kawasaki klr650, i found a print on thingverse but after 4 attemps i noticed that the threads are just completely out of spec with the female side in the carb, im not sure how much but if someone could just edit the threads and give them some clearence thatd be great, im on too much a budget to just buy a replacement but also just dont want to admit defeat just yet, im planning on getting into CAD myself but havent bought fusion yet. i believe the thread size is m12 by 1.0 it may need 5 to 10 thou of more clearence than it comes with, not sure how off it is..

Im somewhat new into modding cars/motorcycles and im wondering where i can find like sheet metal and polyurethane(for bushings for ex:) and stuff like that to make custom parts(engine mounts, a lift kit which i want to make for my civic, brackets and bushings) and just stuff for fabrication in general like metal to shape and weld for stuff. this is a pretty broad question but i searched the sub and couldnt exactly find what im looking for.
