This is a small cart that can store whatever you want with easily customisable shelves.

Specifications:

Dimensions:  420(L) x 236(W) x 475(H)

Max Shelf Load: 60 kg

The overall dimensions of this cart can be easily adjusted by switching the shelf boards and support columns. However, it must be noted that each board-pole interface should hold only 60kg - note: this is to the best of my calculations and could be wrong.

Materials:

1x - 16 x 16 x 2000 mm dowel (400mm for the verticals, 200 for handles)

4x - 25mm dolly wheels (this is up to you and can be switched out)

3x - 380 x 230 mm wooden boards (I used cheap cutting boards as I didn't have space to work with large boards)
