QIDI X-Max Adjustable Internal Spool Holder (6201 Roller Bearing)

prusaprinters

<p><strong>Update November 14, 2021</strong></p><p>Added a new version of the base adapter that should fit newer printers. I am unable to test it myself but it should fit based on feedback from a user. Thanks CFox!&nbsp;</p><p>This is the new file:</p><p>internal-6201-roller-bearing-base-1.2.stl</p><p><strong>About</strong></p><p>The Adjustable Internal Spool Holder for QIDI X-Max works with most filament spools up to 1 Kg. It might also fit the X-Plus but I don't have one so I can't check compatibility. The internal spool holder is useful if you want to keep hygroscopic filament warm and dry during printing of Nylon for example and you don't have an external dry box.</p><p>The spool holder uses a common 6201 roller bearing (search for 6201ZZ or 6201RS, I bought 2 for €4). The holder is attached with an M10 bolt where the stock internal holder goes. The bearing will move freely but the spool is using a simple friction break to prevent it from spinning too fast.</p><p>The filament is guided though a filament guide that goes through the top rear of the printer, just above the circulation fans. If you don't have a hole in the top rear of your printer (see picture number four under Post-Printing below) you can instead print and use the Bowden Connector: "qidi-xplus-xmax-bowden-tube-connector-1.0.stl". Just mount it to the extruder cover with a 20 mm M3 screw and use a 6 mm bowden tube between the internal filament guide and the top cover. See Post-printing for pictures.</p><p>Like I mentioned, the roller bearing is using a friction break, preventing the spool from spinning too quickly during sudden and long printer head movements. You can also print and use the optional "Roll-Off Savers", one on each side of the spool, to minimize the risk of filament jumping over the spool, although it's unlikely it will happen with this system, even with new spools.</p><p><strong>BOM - Bill of Materials</strong></p><p>1 x 6201ZZ or 6201RS roller bearing<br>1 x M3 screw (10 mm)<br>1 x M3 screw (20 mm)<br>1 x M10 bolt (45 to 65 mm long)<br>6 mm filament tube (use the black ones that came with the printer or a longer one)</p><p>(If you want to you can use a longer 6 mm filament / bowden tube for the filament guide between the printer and the top cover so that it's fully enclosed, it's what I use).</p><p>What to print</p><p><strong>Print the following parts:</strong></p><p>internal-6201-m10-to-m12-spacer-1.0.stl<br>internal-6201-roller-bearing-base-1.2.stl<br>internal-6201-filament-guide-through-case-1.0.stl<br>internal-6201-spool-holder-top-1.0.stl<br>internal-6201-spool-holder-bottom-1.0.stl<br>qidi-xplus-xmax-top-cover-1.0.stl</p><p><i>Optionally, print these parts as well:</i></p><p>qidi-xplus-xmax-bowden-tube-connector-1.0.stl<br>internal-6201-optional-roll-off-saver-1.0.stl (print two of them)</p><p><strong>Print Settings</strong></p><p><strong>Printer:</strong></p><p>QIDI Tech X-Max</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>No</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2 mm</p><p><strong>Infill:</strong></p><p>20%</p><p><strong>Filament:</strong> Fillamentum ABS Traffic Red&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>Most parts will be fine at 15-20% infill.
