Quad Fidget Gears

I've enjoyed the challenge of trying to print kasinatorhh's fidget gears and I thought to myself, wouldn't these be even cooler if there were four sets of gears instead of two? Double the gears = double the fun!
Along the way I also made one little enhancement to the original, I enlarged the axle holes so that I could use cut pieces of 1.75mm filament for the axles. This means there's no need to print those tiny axles; just snip off a few lengths of 1.75mm filament. You want them to be roughly 13.5mm long but I'm sure you have calipers and can figure that out.

Instructions:
Print out 2 of each gear model (for a total of 8 gears) and one of each of the holders.
The more precise the better. I like to use a 0.2mm nozzle with super thin layer lines to really kick up the detail and the smoothness.
Cut 4 lengths of filament to use as axles so that they're short enough to fit entirely within the casing and not interfere with the outer gears.
Getting these to spin will almost certainly
