This is a small modular plate rack I designed to organize the plates in my cupboard.

it is designed with a 20mm space between each "spine", with a 10mm width and a 30° angle.

Each segment has 4 spaces for plates, and a front and/or back joint to connect it to other pieces, in particular:

• front only has the back joint
• back only has the front joint
• middle has both

the top of the joint is measured to receive an M3 nut, with the other piece sliding inside and an M3 bolt coming from under to secure. I used M3x16, without tightening all the way to have the bolt sit flush.

Two pieces are joined by a link that fits in the hole in the middle. All tolerances are 0.1mm which on my printer makes it fit snug.
