Making a Wood Rolling Shelf DIY | Стеллаж на колесах своими руками

The first video on this channel and the first experience in creating such content, so I will be grateful to reasoned criticism, questions, requests, comments!
The idea of ​​producing such a rack appeared a long time ago, since it is an excellent solution for saving space in a room and decorating it at the same time. And the wheel supports also make it mobile, which is very convenient in a small area.
For the manufacture of the shelving, I used scraps of building materials that were left over from the construction of the summer house, so I did not indicate the sections of the parts anywhere, since they are not standard.
If someone has a desire to repeat my work, write in the comments, I will send you a file with a 3D model.
