Ender 3 S1（反向适配器）原装线轴座

For a given occasion, I needed an inverted filament holder. But since I wanted to continue using the original parts, I designed a simple adapter.

It simply slides into the existing holder and can then be hooked in the same way, facing forward. In addition, the elevation of the holder can also be used when you have mounted the LED bar of the S1Pro. The adapter sits really nice and tight and definitely keeps the coil in place.

In addition, the filament guide for the filament sensor is better than in the usual orientation. You can also see it well in the photo that the filament now runs dead straight to the extruder. Therefore, the adapter is a successful alternative and has convinced me in any case.

For the filament sensor holder, I use the one from "pakkko". You can find it for free on Cults. This one serves its purpose for me anyway and I prefer it to the original mount.

I decided to use PETG for the printing. I printed with a 0.4 nozzle. I can recommend the following settings for this.

Layer thickness: 0.2

Line width: 0.5

Outer wall line width: 0.4

Inner wall line width: 0.65

Fill line width: 0.4

Walls: 5

Filling density: 15%

Filling pattern: Zigzag

Gradual filling layer thickness: 3

Stepwise fill layer thickness height: 1.5

Support: None

I'm attaching another screenshot so you can see what it looked like on my end.
