Mingda Magician Filament Spool Double Riser Roller

thingiverse

My school had a surplus of proprietary spools for other 3d printers which were not able to use the center post for traditional spool holders. Thus, I used Tinkercad to remix the Mingda Magician X Filament Holder Riser from chippymiller49.608ZZ bearings x 4 are needed for this project.Update 12/22/2023: I re-positioned the rollers such that they are farther apart so as to increase the stability of the spool.Update 12/30/2023: I have uploaded two files for the base of the double roller: a file for the Mingda Magician Max and a file for the Mingda Magician Pro. The Mingda Magician Pro does not have a handle, so the base of the double roller is perfectly symmetrical and wide enough so that the spool will not fall off of the rollers when the spool gets low on filament and becomes lighter. The Mingda Magician Pro and the Mingda Magician Max have handles on the crossbar connecting the two Z-axis risers. Thus, the spool holder for the Mingda Magician Max is slightly assymertical as the position of the spool holder is not perfectly in the middle of the outside end of the crossbar and the beginning of the handle (1.5mm off on the Mingda Magician Max). However because the roller base terminates perfectly with the outside end of the crossbar, I kept it asymmetrical. I do not own a Mingda Magician X, so I don't have a roller base made for that yet...however I know who does have one and I will get the measurements and create the base as soon as it is convenient.ALWAYS POSITION THE FILAMENT FEEDING THE EXTRUDER BETWEEN THE ROLLERS SO THAT YOU DECREASE THE LIKELIHOOD THAT THE SPOOL ROLLS OFF OF THE HOLDER. I have been using this holder and have not had the spool come off of the roller, even when the printer has emptied the spool.
