Position of filament spool on Ender 3V3 Plus

Simple question. Is it possible to mount the spool on the top of printer, in order to reduce the footprint?

Of course you can. There are plenty of fixtures on the cloud for this, or you can create your own. For example: Ender 3 V3 Plus top mount spool holder and run-out sensor | 3D models download | Creality Cloud

OK, thanks. Apparently the filament sensor needs to be moved. What does it involve? Any wiring issue?

No. Only the sensor mount was on short screws, so it didn’t hold. The solution is to use a longer screw or a different type of sensor mount.

OK, Thank you.
