Filament Roll Holder for Creality's "Large Enclosure"

prusaprinters

When choose or not choose this model?A spool holder that attaches to the structure of Creality's “Large Enclosure”.I designed this because I bought some larger / heavier spools which didn't fit the original spool holder of my Ender 3 S1 Pro.At the moment, I have two of these sets in use - each fitting two small 750g spools or one large 2kg spool. Tested with spools from Colorfabb and Prusa.The way it is mounted to the enclosure, filament is best fed from above into the extruder. This system works well for my Ender 3 S1 Pro, but might cause a problem for other printers used within the same enclosure.So you might need additional parts from someone else, alter the design until it suits your needs or search for another design that works better in your case.It could also fit Creality's “Small Enclosure” depending on the diamenter of the structural parts it uses and how much place there's left in it with your setup.Two advantages of my design compared to a spool holder with bearings (for example the original one of the Ender 3 S1 Pro) I observed are on one hand that filament only unspools if it's supposed to and on the other hand that it reduces the weight on the frame if there's no spool attached simultaneously to the printer.How to print?You will have to print the clamp two times and every other model only once for a working assembly. The roll support and the stabilizer / spacer are printed vertically while the clamp and the bar are printed horizontally. Check if everything is oriented as needed and touches the build plate where it should.Only the clamp should need supports for the mounting points of the bar. It was very easy to remove in my case.Except for the roll support, everything can be printed with 2 top and bottom layers and 15 to 30 percent infill depending on your preference in PLA.The roll support needs to be printed with detect thin walls activated - no support, no infill, no top / bottom layers and only one perimeter I think.I suggest printing it last and checking with the dimensions of the other parts before printing to make sure it uses enough space between the two clamps, because I don't remember if I scaled it in Z for my assembly. Edit: Looked at it in Cura and it seems to have the right size.For layer height, you should be able to use 0.2 or 0.3mm or anything inbetween.Tested with Cura 4.13.1.How to assemble?<ol><li> Disconnect the top structure of the enclosure left or right in the center, depending on  which side you  want to mount the holder to the frame</li><li> Slide one clamp on the left half of the structure</li><li> Slide one clamp on the right half of the structure</li><li> Slide the stabilizer / spacer on one half of the structure aligning the cutout with the  metal pin</li><li> Push the stabilizer back far enough so that you can easily reconnect the two halves of  the enclosure's structure</li><li> Now slide the stabilizer middle section roughly above the point where the two  strucutural parts of the enclosure connect for maximum strain relief</li><li> Push the two clamps each flush to the the left respectively right side of the spacer</li><li> Then, you have reached the point where you can slide the roll support over the bar in a  way, so that the two cutouts are not covered</li><li> Place the spool the holder is supposed to hold on the roll support</li><li> Attach the bar to the clamps by aligning the cutouts with the pins</li><li> Make sure it is sitting well and can't move left and right, so that it won't fall off</li><li> Check and assure that the aluminum tubes of the enclosure (earlier referred to as “structural parts”) are well secured inside the angled brackets of the enclosure</li></ol>Note: <ol><li> Especially for the clamp, a sufficiently large and level printbed is required - on my Ender  3 S1 Pro, if sometimes have problems with the leveling closer towards the corners. If  that's the case for you aswell and it only concerns some corners: Make sure your bed is  leveled to the best of your knowledge / skill and rotate the part so that the least printed  area possible is close to the concerned corner(s)</li><li> Ensure your bed adhesion is good enough for all parts, use brim if necessary, Z offset  should be well dialed in</li><li> In order to be able to disconnect the aluminum tubes that support the “tent” (the  enclosure), you need to open the zipper of the enclosure on the side, where you want to  mount the spool holder and push it over the corners for the installation process</li><li> I don't guarantee anything for this spool holder. Print it at your own risk and only use it, if  you think that it is stable enough for your use case and if you think that the enclosure's  structure can bear your desired load</li><li> Print time 5-10 hours on a regular printer depending on layer height and speed</li></ol>
