Summary

PREMISE

I needed a spool holder for my Raiscube R2, so I browsed Thinghiverse seeking for it and I found this https://www.thingiverse.com/thing:2809786 of Jankito. Sadly the print cannot be easily setted with that model orientation, and the model itself is not optimized for structural resistance and lightness: for this reason I designed this new model attached.

Although I've not "used a part, or changed the look of, an other user's thing" (as the "This is a Remix" button says), Jankito's model has been the inspiration for this result. Please consider to also take a look at it.

THE MODEL

It is optimized for a lightweight design: its holes left a few vertical structures so to sustain the deformation induced by a large load: although it is unlikely that the user loads more than 1 kg of filament at a time, still there is enough space for more spools (130 mm from side to side).

All the components can be printed without supports.

In order to make the structure firmer when mounted on the 3D printer i designed also two frontal stiffeners to be chosen according to the user's needs: one has a buttonhole to make the filament flow trough it and not to move too much laterally; the other one is for users who print very high models and need to exploit the full height available (in such a case it is recommended not to make the filament flow from the single position of the buttonhole because it would be bent too much by the extruder).

EDIT 11 March, 2023

I've added holes in the coupling between the frontal stiffener and the lateral supports so to let the maker to connect the parts with a bolt M3 x 20 (you will need two of them and two nuts).
I've also removed the model of the frontal stiffener without the buttonhole, because it simply was not useful (or rather, the one with the buttonhole is far more useful because it makes the wire pass through the printer's cables without forcing them sideward).
