Looking good. In regards to files there is a huge variety of jewelers/needle files sets out there that I think would fit the bill for what you do. Having used them for 35 years in the aircraft instrument repair business I can heartily attest to their usefulness. They come in 6 or 12 piece sets with a medium,. fine or xfine finishes and single or double cut faces. The best quality ones considering the fine work you do I would suggest you go with Swiss-pattern files, you'll pay lots more for them but you will never regret purchasing top quality. At the least buy a mid range set from a quality name. I don't know if you ever have to make slots in your craft but a slot file is something you may find handy at times. Again, you can go for the best with Swiss made like this for example https://eternaltools.com/products/screw-head-slotting-file I still have mine that I bought back in the 70s
