About this 3D model

I did this design to use in the middle of two shelves using the measures from the video. It is a simple design to use with the normal spool roll and you have to print the spool roll to place in the middle of the "arms". If you need to use a larger spool it just need to adjust the spool roll size on the slicer and move the "arms" to fit it. The curved shape it is to remove a bit of the tension of the momentum created by the filament spool and also to make it more interesting and beatifull. I hope you give a look at it.
