This is an organizer tray for the threading change gears for a Smithy Midas 1220 LTD lathe. All slots are marked with the gear tooth count. There are spots for all gears, including gears currently in use on the machine. Hopefully it makes thread pitch changes easier for someone. It is oversized at 6"x6" solely to keep things in multiples of 2" for my drawer organization. 10% grid infill appears to be fine. I'm new to 3d printing and fusion 360, plus I recently lost most my usable vision so forgive the crudeness of the model. It is the first in a futile attempt of organizing things in my life with hopes of being able to use them again with vision loss. Or at the very least, know where things are.
