This spool stand if you apply different length of the horizontal tube (power cable PVC tube). Then you can use this as a water hose spool stand, filament stand or dual filament spool stand as well. Simply print out the joints and detach all support out. and use a knife touch up a bit of the pipe opening, let the tube easily slip in.
Since PVC tube has a very low friction and let the spool of filament or water hose spool freely rotation. particular if the filament spool has a little bit jamming also affect the print out some surface area become rough.

1. print out 2 pairs of the left/right stand. this will be used for the stand base.
2. print out 2X top revised. This is the support for the spool axis.
3. Cut the PVC tube (very common for power cable layout and cheap) appropriate. may be 6 inches X 8.
4. slip in the joints per my photo shown
5. finally cut one more 6 inch tube for the axis.
6. Then the product will be completed.
   In case you would like to use this for a large spool. then the length of each tube may be need to increase to fit with your real application.
   ENJOY!
