Concentric Filament Spool Holder for Ender 3 V2

prusaprinters

<p>By using the original spool holder of the Ender 3 V2, the filament spool keeps swinging back and forth while printing. &nbsp;It is sometimes annoying as it makes some noise. &nbsp;Also, a more secure way for hanging the filament spool is needed to avoid the spool from falling down. &nbsp;Hence, this project was designed.</p><p>For the main screw for supporting the whole weight of the filament holder, I printed it by laying it flat on the print bed to enhance its strength. &nbsp;For the nuts, due to clearance issues, I printed them by scaling them to 110% on the X and Y directions so that the nuts can fit on the main screw. &nbsp;There are two types of spool stops, one large and one small, users may choose the one that suit their needs.</p><p>For installation, simply detach the original spool holder and install the main screw and main screw nut into the original installation hole. &nbsp;Then the spool stops, spacer and filament spool nut can be attached while loading the filament onto the holder.</p>
