Spool Holder for ender3

i've designed this spool holder for the my ender3, to replace the original one that is not very flowing. you do not have to make any changes but take apart the old one and put this in place. there are two versions of 45mm and 20mm rollers that allow the installation of reels of different thickness, the system can be disassembled for inserting and unloading reels with a smaller hole, using 3 x 6mm cylindrical magnets to make it easily mountable and dismountable.
