Large aceton shelf for original Prusa i3 3D printers. It can be placed on the printer frame over the electronics box. You can place a 700ml acetone bottle on it. Be careful if the position of the shelf doesn't collapse with the x-axis engine! Pay attention if the shelf is stable. If not, do not place the acetone on it. You can also use this shelf for other purposes of course.
When printing on FDM printer I needed to generate a support structure.
