This is based on a shelving system I saw at work but it was way out of my price range - or at least it was way over priced. So I designed and printed the tube joiner brackets, the shelf brackets and the back panel brackets. The number of items printed depends how tall, how wide, how many shelves, and how many back panels.

In addition to printed parts there are:-

*Ikea Wall Units ^Mild Steel Tube (Metals4U in the UK) ~12mm thick Plywood painted black.

For this particular project I used:- 8x 3 way joiners 12x 4 way joiners 4x 5 way joiners 24x shelf brackets 12x back panel brackets

Also needed is the right size screws for fixing bottom brackets to top of cabinet and fixing cabinet feet. The Ikea unit is a bit strange with its hollow boards so need the right sizes. When fixing the brackets on top I used longer screws on the corners so they found something to bite into. The middle ones going into a 15mm board need to be shorter. I drilled the brackets before screwing them to the cabinet. The cabinet feet are also going into 15mm board, so found some thicker gauge screws (and added washers) from an old Ikea project.

*METOD Wall cabinet with shelves/2 doors, black, Tingsryd black, 80x60x38.6cm ^15.9mm X 1.2mm (5/8"OD X 18 swg) L=326mm (x12) ^15.9mm X 1.2mm (5/8"OD X 18 swg) L=370mm (x34) ~322x365x12mm plywood shelves (x6) ~365x365x12mm plywood panels (x3)
