Trục ổ bi có ren cho Polydryer

Remixing this great design for the polydryer spool holder.  My polydryer boxes were not hold the original dryer box spindle very well as they kept falling on one side causing the spool to jam up during a print.  I found this design and widened the length of the spindle/axle a bit so it fit my dryer box more tightly.   The only issue was there are a few parts to this and when trying to drop them in the polydryer box they tend to shift and come apart so I threaded the spindle rod and flanges so that you can assemble it, put the roll on it and then easily insert it into the dryer box.   Be sure not to overtighten it as it would cause the bearing to lock up.  

There is two versions of the spindle rod, one fully threaded and another one that is only threaded on the ends for the flange.   

Note: if you print 4 flanges you can use them on both sides of the bearing and adjust the width to accommodate different spool widths.

Oh, and the link to the bearings I used on Amazon:

I printed them with ASA so they don't sag in the heat of the drying process,  No supports required, 15% infill is just fine.
