This print is designed to be extended in length quite easily. Also the design allows to adjust the size of the bar for your printers build volume.
In addition you need a cardboard or a thin wood board placed on the stand to form the back of the piano stand.
I used glue to fix the bar on the brackets, but you could also just use double-sided tape.
The perimeter for the bracket was set to 4, this should give them extra strength.
The author marked this model as their own original creation.
