A simple, fully 3D-printed, folding phone stand that requires no extra parts. Recommended at least 15% infill but any settings will work ok. No supports are needed so long as all the pieces are oriented with the flat side down in your slicers.
After printing, insert 1.75mm through the holes to create the joints and trim so none sticks out the side. You may also use glue or a soldering iron to fuse the filament to the edges of the joints, preventing it from sliding out.
The author marked this model as their own original creation.
