I added 3d models for each components in kicad. This took quite a time as i couldnt figure out how to add 3d model into footprint. I have 9 switches and 10 led so had to add the 3d model to each one of them. I tried adding it to the footprint and was even succesfull in that but still the 3d models were not coming into the 3d viewer. If someone has any idea regarding how to asign same 3d model to many pieces of same component in kicad pls let me know in the comments. Also if there is any design change that you think will be helpful let me know.
