Modular Bookend with adjustable stands.
Each book, manga, CD or whatever will be held straight very easily by the little triangles, which automatically create individual sections for whatever you place in it.
Everything is printed in place, so the print requires good accuracy and flow calibration, so make sure that your 3D printer is well adjusted.
Notice: Pay attention on strong and firm support structures with good layer adhesion. In many testprints the supports got loose and caused fails.
Use brims that are wide enough. I also printed the Support trees with 2 walls, so they got more stable.
The author marked this model as their own original creation.
