The Bookholder is designed to clip on a 2cm thick wooden plank, like in this case, an Ikea bed.

The infill setting is not relevant, because the volume is really thin and almost nothing is hollow in order to use a infill.

I would recomment the use of PETG as a printing material, because it will not break easily, compared to PLA. The mesh is quite thin, but when printed with a strong material, will withstand quite a lot.

It is necessay to use supports to print the clips on the top.

Printing time: ~16h
Material used: ca. 200g PETG
print in place: yes

have fun and enjoy :)
