This is a recreation of a popular design. I created this because other designs do not distinguish between 1.5mm and 1.0mm sheets, leaving the thin sheets too loose.
Drag individual sheet holders into your slicer as desired. By ensuring that the models touch (or overlap), the slicer will create a single object.
The Fusion 360 file is included if you want to further customize the design.
The author remixed this model.
