These brackets are for new single-core cables that are rolled up in a carton. With these brackets, empty Prusment rolls can easily be converted into cable reels and no expensive finished product is necessary. The holders can be fixed on the wall or on a mobile trolley. The rolls are centered and supported, so that the cables can be unrolled quickly.

This bucket holder costs little compared to ready-made solutions and you can use old filament rolls and do not have to discard them.
A comparable stand costs between € 4,000 and € 6,000 for 40 rolls. The self-made stand with the entire printing material and the frame does not even cost 500 € for 80 rolls.
So it is a very inexpensive solution that also looks great.

The screw is based on the "Universal Auto-Rewind Spool Holder (MM)"
