Eibos Easdry Spool Roller/Holder

Original Model lacked a way to lock the two pieces together which made it super annoying to get the spool in because one side would fall over or not align properly. I added the center screw so that it can lock and slide in as one piece which I have tested and it is amazing to not worry. If you have different width spools, you can spin it around the center piece to make it wider or smaller with ease. Also modified it to use M3 screws as I have lots of smaller M3 screws and only big M4 screws. M3 is easier. You can maybe get away with PETG but I printed mine out of ASA. DO NOT USE PLA! This will fit Bambu Lab and Polymaker spools easily. I also use Flashforge spools but you have to loosen the bearing screws a bit because its thicker.
