For whatever reason the spool holder for the ender 3 (pro) is mounted in a way that the spool has to be put on from the backside of the printer. This can be a hassle in tight spaces. So I designed a bracket where you can mount the holder inverted.
I use the spool holder from HugoHuge: https://www.thingiverse.com/thing:3020026 and using my bracket the spool center-line is also in line with the extruder now, not offset to one side.
There are two versions:
Both simply slide on the top 2020 extrusion of the printer.
