I designed this Simple Arches Bookend in SOLIDWORKS for the Printables Bookends contest (07/004/2023).
It's an easy print, without supports, already orientated correctly, in STEP & STL & 3DM files .
(09/004/2023) Update: I added another model that fits the style so the two can now be combined.
Slicer: Prusa slicer
Design software: SOLIDWORKS
Enjoy
The author marked this model as their own original creation.
