Stand for which the idea was born out of necessity - I do not like books lying apart, especially at work where I often use them.
In addition, a cool exercise in FUSION 360 which I really like and recommend.
The model is not correctly oriented - but it is easy to turn it around.
In addition, the printed page is a mirror image of the original model and I did not post it
I added a file in the STEP format for easier remixes.
ROSA 3D PET-G
Two outer layers as a minimum and looks better with non-transparent material.
