Spool holder adapter for Creality Ender 3 V3 (Plus)

The Creality Ender 3 V3 (Plus) comes with a detachable spool holder that makes the printer quite wide. I found an adapter to turn it 90 degrees, which makes it more convenient. However, it was not strong enough, so I redesigned it. I provide three options:

1. 90 degrees adapter with filament runout sensor
2. 90 degrees adapter with PTFE push fitting mount
3. 90 degrees adapter

Compared to the original model, I replaced the mounting location for the original spool holder with two M5 bolts (approximately 20-25 mm) and two M5 nyloc nuts. This makes it easier to print, while being a bit more sturdier. Make sure that the existing bolts fit correctly. If you push it too hard onto the existing bolts, it might crack. The adapter is a bit thicker, to make room for the nyloc nuts. Therefore, it isn't flush with the frame.

For option 1, you will need two M3 brass inserts (outer diameter 4.5 mm, 4 mm height). You can reuse the existing M3 bolts provided with the filament runout sensor. You will also have to extend the original filament runout sensor cable, or create a new one that you directly mount onto the mainboard (that is what I did). This option allowed me to have a better solution for snapping filament and cable management (see photos).

Option 2 is for the situation where you want to route filament through a PTFE tube and need a way to fix the tube. I used a push fitting with a M6 thread, which I bolted onto an M6 nut that I glued into place. This way, I could easily remove it from the mount. This option is only ideal if you plan to relocate (or replace) the filament runout sensor.

The last option is just the 90 degrees adapter, but improved.
