Notebook holder.step

Simple Item to hold my notebooks upright. Holds 3 notebooks. I couldn't find anything remotely close on any website. I printed with 15% infill. with PETG. I printed with bottom layer thickness of 3 MM so it was less likely to flip over. I don't know if necessary. I used PETG from Sunlu. Sliced with OrcaSlicer and then printed on my Anker M5C. Took me 8 Hrs to print but YMMV.
