QIDI X-Max X-Plus Adjustable Spool Holder

<p><strong>About</strong></p><p>The Adjustable Spool Holder for QIDI X-Plus and X-Max works with most filament spools up to 1 Kg. It uses common 608 roller bearings (search for 608ZZ or 608RS, I bought 4 for €4) for a smooth rotation of the filament spool. The spool holder is moved back slightly, allowing for larger spools and for the optional roll-off saver. If you don't have any roller bearings you can print and install the rod extenders instead, it will not move as smoothly but should be fine until you can get your hands on some 608's.</p><p>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 the tall version, even with new spools. Make sure you feed the filament from below the spool through the black filament guide tube.</p><p><strong>BOM - Bill of Materials</strong></p><p><a href="https://s.click.aliexpress.com/e/_ACCns2">2 x 608ZZ roller bearings</a><br>1 x M3 or M4 screw and bolt (15 mm) (optional, you can use the stock screw and nut)</p><p><strong>What to print</strong></p><p>Print the following parts:</p><p>external-spool-holder-top-1.0.stl<br>external-spool-holder-bottom-1.0.stl</p><p>If you're using very wide inner diameter spools you can print these instead:</p><p>external-spool-holder-top-wide-1.0.stl<br>external-spool-holder-bottom-wide-1.0.stl</p><p>Also print these parts:</p><p>external-rod-holder-left-1.0.stl<br>external-rod-holder-right-1.0.stl<br>external-608-roller-bearing-housing-1.0.stl (print 2 pcs)<br>external-608-roller-bearing-wheel-1.1.stl (print 2 pcs)</p><p><i>Optionally, print this part as well:</i></p><p>external-optional-roll-off-saver-1.0.stl (print 2 pcs)</p><p><i>Also optionally, if you don't have any 608 bearings yet, print these:</i></p><p>external-optional-rod-extender-1.0.stl (print 2 pcs)</p><p><strong>Print Settings</strong></p><p>Printer:</p><p>QIDI Tech X-Max</p><p>Rafts:</p><p>No</p><p>Supports:</p><p>Yes</p><p>Resolution:</p><p>0.2 mm</p><p>Infill:</p><p>20%</p><p>Filament brand:</p><p>Fillamentum</p><p>Filament color:</p><p>Yellow</p><p>Filament material:</p><p>ABS</p><p><strong>Notes:</strong></p><p>Most parts will be fine at 15-20% infill.

It should be a tight fit. If it doesn't fit, sand the inside of the edges slightly until it does. Move it to the middle of the rod. Install the roller bearing housing and push in the roller bearing on both sides of the rod.</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/82016/rich_content/7b6b2303-cba3-40bb-a649-badbb2aba4e3/dsc_5370.jpg#%7B%22uuid%22%3A%22b023998b-5c9d-4d14-b7f4-425d7ad4a338%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p>Install the spool and secure with the spool holder (named bottom).</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/82016/rich_content/8e6d9d61-ee4f-4261-8834-56e848061afc/dsc_5371.jpg#%7B%22uuid%22%3A%22f2777cc8-a0a1-448f-81f6-c7d70bcfa4eb%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p>Drop in the roller bearing wheels.
