Bộ Vòng Xoay Đa Tầng [Single Extruder, Không Cần MMU]

In the images, there are great results with tri-color filament and putting gold layers as the two layers on the outside section. The layers are explained in the table below. Reference the picture for the 180 twist for the middle layer.

It is worth adjusting the speed if you have picky filament. I needed to slow my top-layers down a bit, but it turned out great.

In the pictures, I used the rest of a red-green-blue filament, but have used the method below with great results.

Use the same filament from layers 1-13 but when you re-load it, turn it 180 degrees from the horizontal orientation before you reload (see picture yellow-red vs blue-red as it aligns with the input)

Use the same orientation as the first layer or rotate it to a different degree for a even more fun effect!

DONE!

I call it the “end of day work from home” print. Start it before the last meeting of the day, change it after the meeting, get ready for dinner, change the filament, come back from dinner, change filament, then change filament as I'm winding down for the evening.
